In 1876, with $700 saved from their wages at Heyman’s firm, they founded the Weissbein Brothers and Company Bank.

Here, they sold life insurance, real estate, stocks and bonds and interests in local gold mines.

They bought gold and also worked as pawnshop brokers.

“To instill confidence, the Weissbeins borrowed wooden spools from their brother-in-law and wrapped them so that they appeared to be coins and placed them in their safe to impress potential customers.” — Michael Janicot, WSJH

Among the Weissbein Brothers’ holdings were numerous mining claims: the Central North Star Quartz Mine, the General Grant Quartz Mine, mineral lots on Kate Hayes Hill, the Gold Flat Consolidated Quartz Mining Company, the Potosi Quartz Lode mining claim, the Pittsburg Gold Flat Mine Company and the largest shares of the Work Your Own Diggings (W.Y.O.D.) Mine.

Both Weissbein brothers purchased real estate in the Grass Valley area.

Joseph Weissbein built a Victorian mansion at 428 West Main Street in 1893.

This home remained in the family until 1940.


In 1902, the Weissbein brothers relocated to San Francisco, where they continued to invest in real estate.



The Weissbein Brothers devoted time and energy to the preservation of the Grass Valley Jewish Cemetery.

They were later honored when the street leading up to the cemetery was renamed Weissbein Avenue.

In San Francisco, Joseph Weissbein and his family were members of Congregation Emanu-El.



Jacob and Joseph Weissbein were members of B’nai B’rith Garizim Lodge #43.



In 1891, Joseph Weissbein married Harriet B. Wolfe (b.1871?).

Together they had two daughters, Rose (b.1892).and Beatrice (b.1894).


In 1915, Joseph Weissbein died when the Pittburg Gold Mine caught fire.

It was suspected that he was murdered by someone who had been setting fires to various mines in the area, but the case was never resolved despite Jacob’s offer of a $1,000 reward.

Social Life in the Gold Rush Country — 1859

Grass Valley, California March 18, 1859—The ball of the Hebrew Benevolent Association of this place, Monday night, was well attended, notwithstanding the night was one of the most stormy of all this stormy winter. Everything went off well and pleasantly. The dance was continued into the small hours. A friend reminds us that we forgot to make the common appropriate quotation:

“Soft eyes looked love to eyes which spoke again; And all went merry as a marriage bell.”

—The Nevada National, Grass Valley, Saturday, March 26, 1859, WSJH Vol. 5, #3.
