Fredrick Stephanus Watermeyer (14 April 1828 - 28 August 1864), informally known simply as "Fred" or "Frank", was a journalist, advocate and a prominent Member of the Cape Legislative Assembly.
He was meticulously schooled as a child so that, although he was Afrikaans speaking, he was soon described as "one of such unmistakably English education as an old Kapenaar could possibly have."
Frank Watermeyer was among the first Cape advocates to be called to the bar after a purely local examination (instead of having to go to Europe).
Watermeyer's victory for William Long led to the downfall of the judicial basis of the Church of English in the various colonies of the British Empire.
He founded and edited the anti-government Cape of Good Hope Observer in January 1849, to fight the policies of the British Colonial Office during the Convict Crisis.
Other newspapers he edited were Het Volksblad, the Cape Town Mail and The South African Commercial Advertiser (in 1850-51 while Fairbairn was in London).
