William Ponsonby McMahon (1852 – June 1933) was founder of a Catholic newspaper Tribune in Melbourne, Australia in 1870.
McMahon was born in Victoria, and started adult life as a schoolteacher, and moved to Tasmania, where he spent several years as a newspaperman.
[1] In November 1870 McMahon founded the original Tribune newspaper for Melbourne Catholics,[2] but it failed at an early date.
The title was revived in 1900 with The Tribune, subtitled "A Journal of Information and Literature" as a Catholic weekly, and McMahon was with the company from the start, or shortly after, and served as publisher and editor for 19 years.
[3] McMahon married Tasmanian-born Mary Catherine Murphy ( – 7 July 1909), and lived at 35 Gipps Street, East Melbourne.
