Pate was born in
Pender,
Nebraska, to Richard E. Pate and Rachel Davis Pate, of
Welsh and Irish ancestry respectively. He was the oldest of seven children, three of whom died in infancy. His family moved to
Denver,
Colorado, when he was three years old. He graduated from East Denver High School in
Denver,
Colorado, in 1911, then left Denver for
Princeton University. At Princeton he was a member of
Phi Beta Kappa, worked on the undergraduate Red Cross Committee, and earned a bachelor of science degree in
mathematics and
physics in 1915, with high honors. He went to work for the First National Bank in
Hartley,
Iowa, where his uncle was president, immediately after graduation and stayed until the United States joined
World War I. After a great deal of persuasion, he worked for Herbert Hoover's
Commission for Relief in Belgium, which began a lifelong friendship and collaboration. Pate worked for
Standard Oil of New Jersey in
Poland from 1922 to 1927 doing financial and sales work. He married Jadwiga Mankowska, a Polish socialite, in 1927, managed Polish import and banking business, and returned to the United States in 1935 as an
investment banker and businessman. Missing her family and home, Jadwiga divorced Pate in 1937 and returned to Poland, but the two remained friends until her death in 1960. ==UNICEF==
