The Ugly Broad

I’ll say it: the second half of the 20th Century will go down in history as the time when contemporary architecture went to hell. From the 1960s onward, rarely ever did a newly constructed edifice improve upon what was there before.

The example below shows the southwest corner of the intersection between Grand Avenue and 2nd Street in Downtown Los Angeles, where the old Bunker Hill landmark, the Dome Hotel, once stood at 201 S. Grand Avenue. Built in 1905 as a luxury hotel, the Dome was the embodiment of early century Southern California elegance. (Nathan Marsak has more historical information about the Dome here).

The hotel was later converted to an apartment building. Sadly, there was a fire on July 25, 1964, in which three victims lost their lives, and six more were injured. The reasons for the inferno and its severity have come under suspicion, but foul play could never be proven. By October that year, the ruins had been razed, and no trace of the hotel’s former glory remained.

For the next 44 years, the site was a parking lot. And today, it is home to one ugly broad of a building – the Broad Museum, below.

But since it’s surrounded by other unimaginative, modern structures ranging from bland to hideous, at least some might fight the Ugly Broad stands out as … “interesting”.

The La Monica Ballroom (1924 – 1963)

Dated at 1924, this appears to be one of the earliest known aerial photographs of the La Monica Ballroom on the Santa Monica Pier in California. The picture must have been taken shortly before or at the opening of the La Monica Ballroom on July 23, 1924, seen here at the end of the pier. (Dunning Air, Ernest Marquez Collection, The Huntington Digital Library)

Over time, the city of Santa Monica was home to several wharfs and piers, but only the Santa Monica Pier still exists today as a famous historic landmark.

Technically, what we see in the pictures consists of two separate piers. The long, narrow portion constitutes the “Municipal Pier”, which opened on September 9, 1909 and was originally constructed for the rather inglorious purpose of carrying sewage water beyond the breaking waves.

The wide “Pleasure Pier” to the south (on the right side in the pictures) was privately owned and also known as the “Newcomb Pier”. This portion was added by amusement park pioneers Charles I. D. Looff and his son Arthur.

Charles I. D. Looff (born Carl Jürgen Detlef Looff) was a Danish master carver and builder of hand-carved carousels and amusement rides, who immigrated to the United States of America in 1870. Looff built the first carousel at Coney Island in 1876. During his lifetime, he built over 40 carousels, several amusements parks, numerous roller coasters and Ferris wheels, including California’s famous Santa Monica Pier. He became famous for creating the unique Coney Island style of carousel carving. Photo: Long Beach Public Library.

On June 12, 1916, Santa Monica’s “Looff Hippodrome”, containing a carousel opened to the public. Eventually, other attractions included the Blue Streak Racer wooden roller coaster (which was purchased from the defunct Wonderland amusement park in San Diego), the Whip, merry-go-rounds, Wurlitzer organs, and a “funhouse”.

The La Monica Ballroom at the end of the pier and seen in the front of the photograph was designed by T. S. Eslick and featured a Spanish façade, and a French Renaissance inspired interior. It was advertised as “the largest dance hall on the west coast”.

La Monica’s 15,000-square-foot (1,400 m2) hard maple floor offered space for 5,000 dancers and competed with the the Bon Ton Ballroom (later renamed Aragon Ballroom) on what was then known as the “Lick Pier”, located a few miles down the coast in Venice.

Autos crowd the pier during the grand opening of the La Monica Ballroom on July 23, 1924. The event was reported to have attracted 50,000 people producing the first traffic jam in Santa Monica.

In the days before air conditioning, Santa Monica’s Pleasure Pier and its attractions thrived during the 1920s, but faded during the Great Depression.

Subsequently, during the 1930s most of the amusement park attractions were closed down, sold off, or falling into disrepair. Then in 1934, a breakwater was built. This provided protected docking for up to 100 fishing and pleasure boats near the pier, and helped attract new income.

Ca. 1934: A crowd amid beach umbrellas watching two pugilists boxing in an outdoor boxing ring on the beach in front of the Santa Monica Athletic Club. The Santa Monica Pleasure Pier with the La Monica Ballroom and Municipal Pier are in the background.

1936: Crowds of people standing in line at the Catalina Steamer Landing on Santa Monica Pier across from the La Monica Ballroom.

The “Swinging Years” of Big Band Jazz from 1935 to 1945 also brought new crowds to the ballroom. And country music and “western swing” star Spade Cooley began broadcasting his weekly television show from the the La Monica Ballroom in 1948, where the program remained until 1954.

After that, in the summer of 1955, the Hollywood Autocade opened at the La Monica, featuring roughly one hundred famous and unusual cars, including Jack Benny’s Maxwell and a Rumpler Drop Car. Between 1955 to 1962, the ballroom served as a roller skating rink, first as “Skater’s Ballroom”, and later as the “Santa Monica Roller Rink”. A local speed skating club is said to have won many state and regional championships. Speed skater Ronnie Rains became a Roller Derby star. The rink’s operator was a former vaudeville and silent film star, Jack Goodrich, whose daughter, Michelle Goodrich, later became a showgirl in Ice Capades.

The owners of the pier and the ballroom, the Newcomb family didn’t invest enough in upkeep and upgrades to keep the venue from decaying.

And so, the La Monica Ballroom was closed to the public 1962, and demolished in 1963.

Rooftop Boxing

by Reinhard Kargl

(Library of Congress, photographer unknown).

Few details about this photograph can be substantiated. The original caption was supposedly “Radio Pictures Chorus Girls“. This might have been a reference to RKO Radio Pictures Inc., which operated from 1929 to 1959.

The girls were almost certainly entertainers who were photographed while having fun exercising on a Hollywood rooftop — possibly in 1938. The automobiles in the background were likely built in the 1920s and 1930s, and the boxing scene was obviously posed for the photographer. (If you can identify the street address or know any of the girls in the image, I’d love to hear from you!)

Young Abraham Lincoln

by Reinhard Kargl

On this day in 1863, Abraham Lincoln was born into poverty. His birthplace was a log cabin on Sinking Spring Farm near Hodgenville, Kentucky. Raised on the frontier (mainly in Indiana) he was well-read and self-educated, and became a lawyer who opened a law practice in Springfield, Illinois.

I asked DALL-E to simulate what Lincoln might have looked like as a young man during this period of his life, using historical images as reference. Here are the results:

A Los Angeles Roadmap From 1917

by Reinhard Kargl

At the time this map was printed, Los Angeles County was booming with droves of new arrivals pouring in mostly from the East Coast. According to the U.S. Census, the county’s population had grown by 196% during the decade following 1900. By 1910, it had reached 504,131.

At the following census in 1920, the county’s population had swelled to 936,455, which translates to another 85.8% increase over 10 years . Within 20 years of 1900, the population had increased by 5 1/2 times, and 13 times by 1930, ending the decade with a total population of 2,208,492.

Most of the new settlers arrived by railroad. But when the above map was printed, the first automobile affordable to middle-class Americans, the Ford Model T was already in its 9th year of production. While there was a frenzy to build electric tram lines and a bus infrastructure connecting the Los Angeles area, people’s preferences, and the future of personal transportation, were clear. Then as now, people preferred private automobiles over communally shared vehicles the same way as they prefer private bathrooms over public toilets. For much the same reasons, they always will.

By the end of production in 1927, Ford had sold 14,689,525 Model Ts, with the least expensive model selling for just $260. (At the time of this writing, this would amount to an inflation-adjusted price of roughly $5,000 in 2025).

Motoring at the time would have been both fun as well as challenging. Many Los Angeles area roads at the time were still unpaved and rural. The various towns, settlements and cities were scattered about the vast county, and surrounded by farm or ranch land. Cars frequently broke down miles from populated areas. Flat tires were common. The quality of gasoline was unsteady and questionable, and filling stations were a novelty.

Melrose Avenue, 1910

Most gasoline pumps were installed in front of hardware stores, feed companies, livery stables, and a variety of other retailers. Service Town, the earliest known gas station in a modern sense, was built in 1914, three miles from downtown Los Angeles. Before that time, motorists went one place for gas and oil, and other places for lubrication and cleaning, for repairs, or for tires and other accessories.

As automobile sales increased, the demand for fuel led to a more systematic and standardized way of delivering it. In 1914, Standard Oil of California opened a chain of 34 homogeneous stations along the West Coast, and other oil companies quickly followed suit to secure an outlet for their now increasingly branded and advertised products.

The Gilmore Gas Station was one of the first gas stations in Los Angeles. It was located on the northeast corner of La Brea and Wilshire Boulevards. Photo from ca. 1920. (Los Angeles Department of Water and Power).

The signs advertise General Gasoline, Richfield Gasoline, Gilmore Gasoline, Hood Tires, United States Tires and Pennzoil. On the right, an attendant is climbing a ladder. Photo ca. 1928. (Los Angeles Department of Water and Power).

Some of the cities on the road map shown above no longer exist, but were absorbed by Los Angeles or other cities. Examples (on the Westside) are the historic City of Sawtelle and the town of Venice, which were annexed by the City of Los Angeles, and the City of Ocean Park, which opted to join the City of Santa Monica

In 1910, the semi-rural town of Hollywood had voted to merge with Los Angeles in order to secure an adequate water supply and to gain access to the L.A. sewer system. This was very common development at the time, and one which many cities later bitterly regretted.

The community of Pacific Palisades, which was consumed by the horrendous fire of 2025, didn’t exist yet. Neither did the City of Malibu, nor the Roosevelt Highway (later renamed to “Pacific Coast Highway”). But there was a “Beach Road” along the coast, as well as a steam rail line from Downtown Los Angeles to Santa Monica. The latter was how most beach goers arrived to take a few days of respite from the summer heat further inland.

By 1912, some motion-picture companies had moved out West to set up production facilities near or in Los Angeles, one of the first one being short lived Nestor Studios. (Originally known as Nestor Motion Picture Company, then Nestor Film Company, it merged with the Universal Film Manufacturing Company, headed by Carl Laemmle, in 1912).

At the time, the pioneering movie studios were still a newfangled and rather suspect industry, viewed with skepticism by investors, polite society, and cultural guardians alike. They certainly weren’t the main reason why people from all over North America (and Europe) wanted to move to Los Angeles. More important factors were the discovery of vast oilfields and seemingly endless opportunities to make money and fortunes. There was affordable and available vacant land on which one could build quickly, cheaply, and year-round. And all this came with a pleasant climate, and a plentiful supply of fresh meat, fruit and vegetables throughout the year. (This would have been a major draw at a time when heating consisted of building a fire in an oven or fireplace, and electric refrigerators were a rare novelty).

But I would argue that of all industries, it was the motion picture industry which drove America’s rapid motorization in the first part of the 20th Century. Cinemas would soon reach every corner of the country. And there, on big silver screens, huge crowds of people saw all segments of society happily motoring around Southern California. Often in open cars no less, far from snow and ice, and enjoying the joys of personal, individual transportation. To audiences back then, all this looked like magic. And of course, the car industry back east could not have invented a better publicity campaign.

The Garden Of Allah

by Reinhard Kargl

On the left in this rare image of Sunset Boulevard just west of Crescent Heights, taken during the early 1930s, we see the entrance to the Garden of Allah at 8152 Sunset Boulevard. On the right is the Chateau Marmont, which still stands. A house behind the trees in the center would eventually become the Preston Sturges’ Players Club, then the Imperial Gardens, Miyagi’s, and the Roxbury.

About three decades preceding this photograph, the hills to the north were still lined with orange groves. What became Sunset Boulevard was just a dirt road. By 1905, real estate mogul William Hamilton Hay (1865-1946) began dividing and developing 160-acres of land bounded by today’s Sunset Boulevard to the north, Santa Monica Boulevard to the south, Crescent Avenue (today’s Fairfax Avenue) to the east and Sweetzer Avenue, in what is now the City of West Hollywood.

At the originally assigned street address of 8080 Sunset Boulevard, the “Hayvenhurst Estate” occupied a 2.5 acres site fronting Sunset. It was bounded by Crescent Heights Boulevard on the east, and Hayvenhurst Drive (today spelled Havenhurst) on the west. The property’s southern edge formed the city limits between the Hollywood district of the City of Los Angeles, and what later became the incorporated City of West Hollywood. Eventually, the property’s address was changed to 8152 Sunset Boulevard.

The estate had twelve rooms and four bathrooms. The interior finishes were fashioned from Circassian walnut wood which Mr. Hay and his wife Katherine had collected on a trip to the Philippines in 1912. (It is said that the couple personally managed the project). The interior walls were covered in hand-painted canvas and hand-painted. Perhaps unusual for the time, the property included a two-car garage (with upstairs rooms servants).

Completed in 1918, the property stood vacant for several years, as Mr. and Mrs. Hays had moved on to other building projects.

Around that time, the property was recommended to silent film actress Alla Nazimova, who first leased and then bought the estate from the Hays.

Facing bankruptcy, Ms. Nazimova apparently found investors, and had the property converted to a hotel by commissioning 25 villas on the site. In 1927, this became known as “the Garden of Alla”.

Main house interior, date unknown

Not skilled in running a hotel, Ms. Nazimova was forced to sell the money-losing property to a holding corporation, which renamed it to “Garden of Allah”. It was, in its heyday, a bohemian hangout for young creative types flocking to Hollywood’s film industry from all corners of the world. Given the list of guests (see below) and the many stories of rambunctious parties, dubious events and salacious happenings, it was quite the place to be.

The Garden of Allah pool in 1959

Sadly, after losing its luster and falling into disrepair, the Garden of Allah was torn down in August of 1959, to be replaced with the Lytton Savings & Loan main branch. A pristine example of Googie architecture, the bank building was designated a historic cultural landmark in 2016. Nevertheless, it was condemned to demolition by a subsequent ruling, in order to make way for one of the ugly, disjointed monstrosities Frank Gehry’s architectural firm is known for.

Today, nothing remains of the Garden of Allah, except a place in history, the myth, and an imaginary landmark as one of the central locations in the Golden Era of Hollywood.

Charles Lindbergh’s 122nd Birthday

by Reinhard Kargl

Born on February 4, 1902, Charles Augustus Lindbergh would be 122 years old today. Although mostly remembered as an aviator and U.S. military officer, he had a wide range of interests besides aviation – among them politics and international relations.

A prominent member and spokesman of the America First Committee, Lindbergh was strongly opposed to President Franklin Roosevelt’s foreign policy.

(Photo: Charles Lindbergh as a 25-year old, in 1927 – the year of his historical flight from New York to Paris).

Like many of his contemporaries, Lindbergh believed that Soviet communism was by far the greatest threat to America, and thus advocated a neutral stance toward the NSDAP’s rise in Germany.

This was indeed a very popular opinion among the American public at the time, and easily the majority. The way America had been drawn into World War 1 just a little more than two decades earlier played a major role in this.

Lindbergh later wrote:

I was deeply concerned that the potentially gigantic power of America, guided by uninformed and impractical idealism, might crusade into Europe to destroy Hitler without realizing that Hitler’s destruction would lay Europe open to the rape, loot and barbarism of Soviet Russia’s forces, causing possibly the fatal wounding of Western civilization.

Lindbergh died on August 26, 1974. During his life, he had witnessed both world wars (fighting for the U.S. in WW-2, albeit unofficially), the enormous rise of commercial aviation, the first nuclear weapons and the beginning of the nuclear age, the electronics revolution, the Cold War and the split of Europe into a free market Western part and a communist Eastern part, the Cold War’s proxy wars in Korea and Vietnam, the Cuban missile crisis, the culture wars of the 1960s, and the space race culminating in the first manned moon landings.

Almost 50 years have passed since Lindbergh’s death. Today’s world includes the Russian invasion of Ukraine, North Korean saber rattling against South Korea, the People’s Republic of China openly talking about (and practicing) the invasion of Taiwan, Iran’s nuclear ambitions, and the aftermath of the attack on Israeli civilians originating from the Gaza Strip — all of which could easily compound and escalate into a global conflict with the potential for nuclear weapons being used.

I often wonder how, if he was alive today, Charles Lindbergh would judge the contemporary geopolitical situation, and the state of America and Western Civilization, in 2024.

What’s a Molotov Cocktail?

by Reinhard Kargl

The term “Molotov cocktail” came from the Russian invasion of Finland in 1939. Finnish soldiers and civilians resisted the numerically far bigger, communist Red Army with home made fire grenades named after Soviet foreign minister Vyacheslav Molotov, Molotovin koktaili.

The term’s origin was a response to Russian propaganda. Molotov was claiming on Soviet state radio that bombing missions over Finland were actually airborne humanitarian food deliveries for their starving neighbors. This was, of course, a blatant lie.

Vyacheslav Molotov, 1945

The outraged Finnish population sarcastically dubbed the Soviet cluster bombs “Molotov bread baskets” in reference to Molotov’s propaganda broadcasts. And when they began using hand-held bottle firebombs to destroy Soviet tanks, they called them “a drink to go with his food parcels”.

When skillfully thrown against vulnerable points on vehicles (such as trucks, armored personnel carriers or tanks), the little fire grenades were surprisingly successful at the time. So successful indeed that the Finns commissioned the distillery company Oy Alkoholiliike Ab to manufacture Molotov cocktails industrially. It is said that the company made 450,000 of them.

Finland’s fierce resistance and the fighting spirit of its population succeeded in preserving the country’s independence. But it came at a cost of at least 70,000 Finnish lives and large territories, which were ceded to the Soviet Union during the peace negotiations.

Since then, the Molotov cocktail has been a weapon of choice in many conflicts involving civilians against an overwhelming force. For instance, during the Hungarian uprising against Soviet control in 1956, Molotov cocktails thrown by Hungarian street fighters destroyed as many as 400 tanks before the Soviet military crushed the rebellion. Similar fighting occurred in 1968, during the Prague Spring in Czechoslovakia.

Czechoslovaks carry their national flag past a burning Soviet tank in Prague, 1968.

In essence, a Molotov cocktail is a primitive incendiary weapon. It consists of a breakable glass bottle filled with a flammable liquid. A fuse of some sort is attached to the outside and lit before throwing the bottle, which shatters upon impact and spreads the flammable liquid. Various kinds of liquids, fuses and added chemicals have been used, and there are some versions that produce the ignition by a chemical reaction rather than by manually lighting a fuse.

How effective these devices still are against modern military vehicles is highly questionable. Over time, military vehicles have been hardened against this sort of attack. Vulnerable points (such as tires, the cogs on which tank tracks run, air intakes and radiators) have been improved, and there are often fire suppression systems on board. And an effective counter tactic is for convoys to move very rapidly. At the same time, the delivery of a Molotov cocktail (usually by direct throwing from very close range, or by dropping from buildings, bridges or other structures) subjects the combatant to great risk. As in any form of combat, the risk-benefit assessment is very tricky and comes down to probabilities.

Who Discovered Jupiter’s Moons?

by Reinhard Kargl

Usually, Galileo di Vincenzo Bonaiuti de’ Galilei [1564 to 1642] gets the credit for discovering the largest four moons of Jupiter – a most controversial scientific sensation at the time.

But not so fast! As usual, the truth is a little more nuanced.

Today happens to be the birthday of the German astronomer Simon Mayr [1573 to 1624 or 1625], better known under his Latin name, Simon Marius. In Mundus lovialis, his book from 1614, Marius describes Jupiter and claims that he discovered four moons in 1611. According to his claims, he would have made his discovery about a month earlier than Galileo Galilei.

Of course, Galileo was a famous celebrity and well known among Europe’s intellectuals and clergy. He appears to have been unimpressed by Marius and swiftly accused him of plagiarism, causing Marius’ reputation to suffer greatly.

It took 289 years to exonerate Marius. In 1903, a scientific jury in the Netherlands examined the evidence extensively. Its findings, published in 1907 were: Marius discovered the moons independently, but he did not start keeping notes until 29 December, 29, 1609 on the Julian calendar. This date corresponds to January 8, 1610 on the Gregorian calendar used by Galileo and falls on the day after the famous letter in which Galileo first described the moons. Moreover, Marius’ description of the moons’ orbits is superior to Gelileo’s.

So who was really first? We’ll never know for sure, simply because there is no record of the date on which Marius made his initial observation. We only know when he recorded it, and when Galileo recorded his own observation.

It may seem ironic that the names under which the “Galilean” moons are known today are those given to them by Marius: Io, Europa, Ganymede and Callisto. (Galileo had named them after one of Europes most powerful and wealthiest families at the time, “the Medici Stars”).

So what can we learn from this story?

  1. Keep good notes.
  2. Know what calendar to use.
  3. It helps to be famous.
