San Francisco Landmark #33
Sentinel Building
AKA Columbus Tower
AKA Coppola's Cupola
916-920 Kearny at Columbus
Financial District
Built 1907

The Sentinel Building, designed by Salfield and Kohlberg, is a flatiron building clad in white tile and copper. Construction was begun before the 1906 Earthquake and Fire. The framing survived the disaster, and the building was completed in 1907. The top floor housed the real estate brokerage of Political boss Abe Ruef after his release from San Quentin State Prison on charges of graft.

Many San Francisco guides, both paper and cyber, report that Caesar salad was invented here during prohibition, that the original hungry i nightclub was located in the basement, and that the Kingston Trio bought the building in 1959 and recorded here.

The first report is almost certainly false. It is generally acknowledged that Caesar salad was improvised by Caesar Cardini at his restaurant in Tijuana using leftover Romaine lettuce and ingredients that happened to be on hand. According to Cardini's daughter Rosa, the date was July 4th 1924.

A very young Barbra Streisand sang at the hungry i, but Barbra Archives states that the nightclub was in the basement of the now demolished International Hotel.

Regarding the Kingston Trio, evidence suggests that the trio did own the building but that their studio recordings were made at Capital Records Studio B in Los Angeles. The official Kingston Trio website does not mention the Sentinel Building, but architectural critic Allan Temko, whom I trust, wrote an obituary for Rob Moor in the San Francisco Chronicle dated 16 June 1997:

Rob Moor, a Dutch-born businessman who saved and restored the historic Sentinel Building at Columbus Avenue and Kearny Street, died of pneumonia on May 22 at his home at Yardley, Pa. He was 85.

When [the Moors] arrived in San Francisco [in 1957], architect Henrick Bull, who designed a ski house for them in the Sierra, advised them to purchase the Sentinel Building, a late Victorian steel-framed "flatiron" structure, surmounted by a copper dome, which was threatened with destruction at a time when there was little interest in architectural preservation.

Yet the nine-story Sentinel was an authentic landmark on both historical and aesthetic counts because it had been built just before the 1906 earthquake and fire by the notorious political boss Abe Ruef, who later went to San Quentin for his transgressions.

The Sentinel survived the quake and fire, and was put right again. But it had deteriorated badly (although Enrico Banducci's hungry i nightclub flourished in the basement) by the time the Moors bought it in 1958 as an investment and renamed it Columbus Tower.

They never had cause to regret the stylish restoration by Bull, and they sold it at a profit 1 1/2 years later to a successful young singing group called the Kingston Trio. The Trio in turn sold it to Francis Ford Coppola, who changed its name back to the Sentinel and has his office there today. The building is now an official landmark.
