Zeferino Vaz (May 27, 1908 – February 19, 1981) was a Brazilian doctor who led the construction, establishment and development of the Unicamp university, in the interior of the State of São Paulo, Brazil in the 1960s and 1970s.
The main campus is named after Zeferino, who strived to bring together some of Brazil's best scientists to form a recognised research institution.
Shortly after his graduation, Zeferino became professor of Zoology and Parasitology in the Veterinary Medicine School of the University of São Paulo.
Zeferino was responsible for bringing scientists from other universities, and this helped Unicamp become one of the most productive and respected research institutions of Latin America.
Zeferino retired in 1978, but remained president of the Unicamp development foundation (Funcamp) until 1981, when he died of coronary problems.
