Sweeny's paternal grandfather, Charles Sweeny, was an Irish immigrant who made his fortune in mining in the Coeur d'Alene region.[1][3][4] "Bob" or "Bobby" was the youngest of four sons of Robert and Teresa Sweeny. Robert Sr. was a successful lawyer in Los Angeles, before moving to New York City in 1916 to pursue business opportunities and enlarge the family fortune.[1][5] One uncle was Charles Sweeny (1882–1963), a soldier of fortune and officer in various armies.
In 1954, Arnold Palmer beat him, 1 up, in the U.S. Amateur final. Palmer considered this his first major victory and the "turning point" of his career.[7]
Second World War
Sweeny tried to join the Royal Air Force (RAF) as a fighter pilot, but was turned away as he was considered too old at 28 or 29. He was eventually made adjutant of No. 71 Squadron RAF, but managed to become a bomber pilot, flying the Consolidated B-24 Liberator with No. 224 Squadron RAF.[8] He participated in the sinking of two U-boats in the Bay of Biscay within the space of a few days.[9] In the second clash, Sweeny's Liberator was hit, but he managed to return to base on three engines. For this second action, he was awarded the Distinguished Flying Cross in September 1943.[10][11]
Flight Lieutenant Sweeny was given a medical discharge on September 27, 1945, retaining the rank of squadron leader.[12]
Personal life
Barbara Hutton, one of the wealthiest women in the world, was in the process of divorcing her second husband in 1938 and 1939. Newspapers speculated whether Sweeny was to become her third.[3][4] They had a serious relationship, but Hutton ended up marrying movie star Cary Grant in 1942.
In 1948, Sweeny met 18-year-old New York debutante Joanne Marie Connelley. Despite their significant age difference, they married the following year.[13] They had two daughters, Sharon (born 1950) and Brenda (born 1952). However, he divorced her in 1953[13] when she was allegedly caught in a compromising situation with playboy Porfirio Rubirosa.
