. He was awarded the Nobel Prize in Physiology or Medicine
in 1951 for developing a vaccine against yellow fever

), his father Arnold Theiler
was a veterinary bacteriologist from Switzerland
. He attended Pretoria Boys High School
, Rhodes University College
, and then University of Cape Town
Medical School graduating in 1918. He left South Africa to study at St Thomas's Hospital Medical School, King's College London
, and at the London School of Hygiene and Tropical Medicine. In 1922 he was awarded a diploma in tropical medicine and hygiene and became a licentiate of the Royal College of Physicians
of London and a member of the Royal College of Surgeons of England
. Theiler wanted to pursue a career in research, so in 1922 he took a position at the Harvard University
School of Tropical Medicine. He spent several years investigating amoebic dysentery
and trying to develop a vaccine from rat-bite fever
. He became assistant to Andrew Sellards and started working on yellow fever
. In 1926 they disproved Hideyo Noguchi
that yellow fever was caused by the bacterium Leptospira icteroides, and in 1928 the year after the disease was identified conclusively as a virus
, they showed that the African and South American viruses are immunologically identical, after Adrian Stokes induced yellow fever in Rhesus monkeys from India. In the course of this research Theiler himself contracted yellow fever but survived and developed immunity.
In 1930 Theiler moved to the Rockefeller Foundation
in New York, where he later became director of the Virus Laboratory and where he spent the rest of his career.

Between 1940 and 1947 the Rockefeller Foundation produced more than 28 million doses of the vaccine and finally ended yellow fever as a major disease.

Work on yellow fever
After passing the yellow fever virus through laboratory mice, Theiler found that the weakened virus conferred immunity on Rhesus monkeys. The stage was thus set for Theiler to develop a vaccine against the disease. However, it was only in 1937, after the particularly virulent Asibi strain from West AfricaWest Africa

Theiler's Murine Encephalomyelitis Virus (TMEV)
In 1937, Max Theiler discovered a filterable agent that was a known cause for paralysis in mice.
