Thomas Brothers Maps (often written Thomas Bros.) was a map company that published the once-ubiquitous Thomas Guides, detailed spiral-bound road atlases. Before the advent of Google Maps and other GPS-based services, it was common for drivers to have traditional folding paper maps for larger and less frequently visited areas, but to have a Thomas Guide for their home region. The company also produced the infamous redlining maps for the government-sponsored Home Owners' Loan Corporation in the 1930s.
The company was started by George Coupland Thomas and his brothers in 1915 doing drafting, specializing in block maps used for real estate. c.1925 their office was at 1127 Clay St.; later it was at 361 - 17th St.
After George Thomas died in 1955, his widow Camille hired attorney Warren Wilson, brother of later mayor Lionel Wilson, to help run the company. They knew each other from the Christian Science Reading Room in Montclair. In 1962, she sold 75% of the company to him 6 and died later that year.
The company was purchased by Rand McNally in 1998 1 and Wilson retired. The company still publishes Thomas Guides to San Diego County, and Los Angeles and Orange Counties.
The Thomas family was from the Sevenoaks district of Kent County, England, and emigrated in 1885.
