To 50 AD of Albert Einstein


Time, January 26, 1968


Died.  Leopold Infeld, 69, Polish theoretical physicist; of a heart ailment; in Warsaw. At Princeton, during the 1930s, Infeld helped his friend Albert Einstein develop the general theory of relativity; with Einstein he also shared the work of writing The Evolution of Physics, a 1938 text so fascinating to laymen that it hit the bestseller lists. At the University of Toronto, Infeld did pioneer work on the unified-field theory of magnetism and gravitation; then, in 1950, he suddenly returned home to teach - and proved something of a problem to the the Communists, after criticizing Warsaw's scientific censorship.
