Vischer is known for the sketches he made of California in the 1860s and '70s. His most common subjects were the missions and scenes of nature. His early attempts to reproduce his drawings by lithography proved disappointing, which led to his becoming a pioneer in the area of photographically reproduced artwork. He published a number of well-known portfolios, including Pictorial of California Landscape (1870), and Missions of Upper California (1872).
At age nineteen, Vischer emigrated from Germany to Mexico, where he worked as a supercargo -- an officer aboard a merchant ship, charged with the commercial concerns of the voyage. In that capacity, he made many trips up the west coast of America and to Asia.

According to Palmquist and Kailbourn in Pioneer Photographers of the Far West, "In September 1842, Vischer sailed from Acapulco on the schooner California on a combination business and pleasure trip to Alta California, where he made a tour of Sausalito, Sonoma, San Rafael, and Monterey... Vischer concluded his circuit of California with visits to Santa Barbara, Los Angeles, and San Diego. Although he apparently did not sketch the missions and pueblos he visited in 1842, in later years he drew many of these scenes from memory."
