Trevor Clifford OAM (18 April 1927 – 4 May 2019) was an Australian botanist and taxonomist, distinguished for his work on the hybridisation of species and palaeobotany.
[1] After the completion of school, he took employment with the Victorian Department of Education which offered a scholarship to obtain a teaching degree.
Clifford took up employment as a part time tutor in the Department of Botany after graduation and commenced research toward a master's degree on the distribution of eucalypts in the Dandenong Ranges.
[3] After meeting with R. A. Fisher from the University of Cambridge to discuss his research, he was encouraged to prepare a paper for publication which led to him being awarded a scholarship to travel to Durham, England in 1952 to undertake studies toward a PhD for 2 years.
He and Professor William Stephenson collaborated on the book An Introduction to numerical classification, an early textbook on multivariate analysis.
