Alfred A. Hart (1816-1908)
In 1864 Hart may have traveled to Yosemite with Charles L. Weed to make images of the valley for Lawrence & Houseworth. This attribution is based on a group of fifteen negatives of Yosemite that were purchased by the Central Pacific Railroad (CPRR) from Lawrence & Houseworth. The CPRR later published these images and credited Hart as the photographer. Hart may also be responsible for the photographs documenting hydraulic mining in Yuba County that were published by Lawrence & Houseworth in 1865.
