William Beak MBE (15 January 1878 – 5 June 1966) was an Australian cattle breeder and local government politician.

[1] In recognition of his work establishing the breed in Australia, Beak was elected as a life member of the American Polled Hereford Association.

[1][9][10] In 1936, Beak sold his property "The Meadows" situated between Nerimbera and Nankin to the Central Queensland Meat Export Company.

With an interest in stud cattle breeding and carcass judging, Beak published The Key to Divine Designs and their Guidance for the Improvement of Beef Quality in 1956, in which he endorsed the controversial theory of telegony.

[1] This was followed by 1957's Passing on more discoveries by a layman in which Beak claimed a person could judge the internal features of fat steers by tapping them with their fingers and listening for sounds.
