Joseph Aloysius Hansom was an architect active in the 19th century. He worked in the office of John Oates and then, from 1828 until 1834, in partnership with Edward Welch (born 1806, died 1868) designing buildings in Birmingham, Liverpool, Cheshire, Lancashire, North Wales, the Isle of Man, and Yorkshire.
Hansom worked independently after that until 1869, in Leicestershire and Warwickshire in particular. Hansom was the founder of the Builder and the inventor of the 'Hansom cab'.
