Frederick Crist Trump Jr. (October 14, 1938 – September 26, 1981; nicknamed "Freddy") was an American airplane pilot and maintenance worker. The eldest son to realtor Fred Trump Sr., he fell out of his father's favor when he chose to become an airline pilot. Fred Sr. then chose Fred Jr.'s younger brother Donald to take over the family business. Early life Frederick Crist Trump Jr. was born on October 14, 1938, as the first son of wealthy real estate developer Fred Trump and Mary Anne MacLeod Trump in Queens, New York. In 1956 Fred Jr. graduated from St. Paul's School. In that same year his father Fred Sr. donated money to have the playing fields redone and in his honor were renamed Trump Field. Fred Jr. attended Lehigh University and joined a historically Jewish fraternity, Sigma Alpha Mu, even though he was not Jewish. He became president of the fraternity and graduated with a B.A. in business, also completing ROTC and entering the Air National Guard as a second lieutenant. Pilot career In 1958, Fred Jr. met Linda Clapp while vacationing in the Bahamas. She later became a stewardess and asked him for help finding an apartment near Idlewild Airport; they soon began dating. He proposed to her in 1961. In early 1962, they were married in Florida, and she resigned from the airline, which did not allow its stewardesses to be married. They settled in Manhattan and had their first child, Frederick Crist Trump III, in November 1962. The next year, they moved into one of Fred Sr.'s apartments in Jamaica, Queens. During this time, Fred Jr. did maintenance jobs on his father's properties. Fred Sr. wanted his oldest son to be "invulnerable" so he could take over his real-estate business, E. Trump & Son, but Fred Jr. was the opposite in personality. In 1966, Fred Jr. was listed in newspapers as vice president of E. Trump & Son, but he had a difficult time working with his father. Fred Jr. left the company to pursue his dream of being a pilot, quickly being accepted at Trans World Airlines, which created tension with his father. According to Fred Jr.'s daughter, Mary L. Trump (born 1965), her grandfather "dismantled him by devaluing and degrading every aspect of his personality." Both Fred Sr. and Donald mocked him for his decision to become an airline pilot, comparing it to driving a bus
