Aaron Fleishhacker was born in Bavaria, Germany, in 1820.

Along the way . . . .

At the age of 25, Aaron Fleishhacker moved to the United States and settled first in New Orleans.

There he engaged in a general merchandise business.

After a few years he moved to New York City for a brief period until he heard the “Call of the West”, locating in San Francisco, in 1853.

He engaged in general merchandising out in the Gold Country in Sacramento and Grass Valley, California, as well as Virginia City and Carson, Nevada.

“During his residence among the various characters in the mining camps of Nevada, Aaron Fleishhacker, father of the Fleishhacker boys, was known as “Honest Fleishhacker.” The name was well earned and given to him through his reputation of always keeping his word.”  –Rabbi Martin Meyer, 1916

Returning to San Francisco, Fleishhacker established a manufacturing plant for the making of paper boxes, and a general paper business – both of which grew to very large enterprises.

They were also influential in the banking industry with their various banks eventually becoming the Crocker 1st National Bank.

Herbert Fleishhacker was my grandfather’s business partner in developing Pebble Beach. When he and S.F.B. Morse went to buy the Hotel Del Monte and the 20,000 acres of the Monterey Peninsula including Pebble Beach and Pacific Grove, his patrons, the Crockers wanted nothing to do with it. It was 1919 and Mr. Fleishhacker, head of the Anglo Bank, found him the money he needed and became his partner. They were friends for life. –Submitted by grandson, Charles Osborne.

The family was deeply philanthropic and responsible for many of the area’s cultural and landmark institutions including the Fleishhacker Zoo, which later became the San Francisco Zoo and the Fleishhacker Pool in San Francisco, famed as the world’s largest saltwater swimming pool, which remained in operation until 1971.
