George Singer (1847-1908) was involved in bicycle manufacture before his first car was built in 1905 in Coventry.  The company steadily grew, producing a range of small cars both before and after WW I.  In the 1930’s, the firm became involved with motorsport with their Le Mans models.  After WW II, the Rootes Group took over the company in 1955, with cars being based mostly on Hillmans.  When Chrysler acquired the Rootes Group in 1970, the Singer name was no longer used.
