Among the many Jews who settled in Martinez, Simon Blum was outstanding.


Simon Blum was born in 1834, in France.

He had come to this country in 1850, at 16 years of age, and arrived in San Francisco, early in 1853.

In the fall of 1854, Simon Blum  established himself in Martinez, California.

Simon Blum was naturalized in Martinez, in 1856.

Within a short time, Simon Blum’s brothers, Gabriel Blum and Elias Blum arrived in Contra Costa County and became part of the family business.


Elias Blum, born in 1839, be­came a citizen, on May 18, 1861

Gabriel Blum was born, in 1838, and was naturalized, in 1867.



In 1882, at the general merchandise firm of S. Blum & Brothers had sold over one million dollars worth of goods in retail alone.

S. Blum & Brothers also had a grain firm called Fish & Blum of Martinez, plus two stores in Lassen County, in the northern part of California.

An idea of the dealings of S. Blum & Brothers may be had from an 1885 news item which detailed the arrival of four schooners bearing materials for them.

“One car­ried 7,500 fence posts, another had 120,000 board feet of red­wood, the third contained a load of bricks, and the last one carried coal, lime and lumber.”

In 1892, a newspaper reported that forty-five schooner loads of hay, amounting to 12,000 bales, had been shipped that season from the Blum warehouse.

In 1895, the Blum firm began manufacturing brick at Pacheco.

Eventually, the Blum brothers were operat­ing eleven warehouses, four in Martinez, four in Pacheco, and one each in San Pablo, Brentwood and Byron.

These were used mainly for grain and hay storage.
