[2] Feldmann was born 2 December 1944 in Lvov to a Jewish family who managed to get to France immediately postwar.
[5] After graduating with an MBBS degree from the University of Melbourne in 1967, he earned a Ph.D. in Immunology at the Walter and Eliza Hall Institute of Medical Research in 1972 with Sir Gustav Nossal.
[3][4] He moved to London in the 1970s, working first with Avrion Mitchison at the Imperial Cancer Research Fund's Tumour Immunology Unit; in 1985 he moved to the Charing Cross Sunley Research Centre and the Kennedy Institute of Rheumatology (which joined with the Faculty of Medicine at Imperial College in 2000; in August 2011 the Institute transferred to the University of Oxford.
[4] In the 1980s he published an hypothesis for the mechanism of induction of autoimmune diseases, highlighting the role of cytokines.
[7] Feldmann's group demonstrated that diseased joints have far more pro-inflammatory cytokines than normal, and postdoctoral researcher Fionula Brennan identified one of these, tumour necrosis factor alpha, (abbreviated TNFα) as the key.
