John Bracebridge Wilson (13 September 1828[1] – 22 October 1895) was headmaster of Geelong Grammar School in Victoria, Australia.
He then decided to try his fortune in the distant colonies, boarding the Guy Mannering for Melbourne, Victoria, arriving in November 1857.
Determined to retain the students, Wilson rented temporary premises to operate as a private "High School", and was so effective that when the reconstituted Geelong Grammar opened in February 1863 Wilson was appointed head master, a position he held for the rest of his life.
Wilson was a dedicated naturalist, and known as a marine biologist, elected in 1882 a Fellow of the Linnean Society.
His death followed a brief illness; an unostentatious funeral service attended by many hundreds of past and present students was followed by burial at the Eastern Cemetery.
