Alfred Schild (September 7, 1921 – May 24, 1977) was a leading Austrian American physicist, well known for his contributions to the Golden age of general relativity (1960–1975).
Upon the outbreak of World War II Schild was interned as an enemy alien, but later allowed to travel to Canada.
Schild spent the next eleven years at the Carnegie Institute of Technology, where he helped to develop the first atomic clocks.
[6] Kerr had invited Schild to his office to calculate angular momentum in a solution to Einstein's field equations.
Schild clarified and enlarged general relativity through his studies of single-particle motion, quantization, special solutions and the conformal structure of space-time.
