Joseph Trench

Joseph Trench (1815-1879) was an American architect who practiced in New York City and San Francisco in the 19th century.

Trench was born in 1815, but little is known about his early history or training. By 1837 he was practicing in New York, and brought Jasper Francis Cropsey, who would go on to be a notable Hudson River School painter, into his office as an apprentice and draftsman. Several years later, in 1842, Trench took John B. Snook into Trench & Company, and Snook soon became the junior partner in the firm, which was later renamed to Trench & Snook.

Trench moved to San Francisco in 1850 or 1851, and practiced as an architect there, designing among other buildings the Jenny Lind Theatre (1851), which later became San Francisco's City Hall, and the Metropolitan Theatre (1853).Trench also had other occupations, managing the Metropolitan Theatre and San Francisco Hall, and, later, became a prospector and miner.In 1856 he ran a mining operation in Mexico, and he formed the firm Sparrow, Trench & Company to run mines in the Nevada Territory.

Trench, who never married, retired in the early 1870s, and died in East Oakland, California on August 27, 1879.
