Richard Henry Lea and Graham Ingoldsby Francis started the business in Coventry in 1895. They branched out into car manufacture in 1903 and motor cycles in 1911. Lea-Francis built cars, under licence, for the Singer company. In 1919 they started to build their own cars from bought-in components. From 1922 Lea-Francis had a tie up with Vulcan of Southport sharing manufacturing and dealers. Vulcan supplied bodies to Lea-Francis and in return got gearboxes and steering gear. The association finished in 1928 when Vulcan stopped making cars.
