Editing Spencer Tracy (section)

===Marriage and family===
Tracy met actress [[Louise Tracy|Louise Treadwell]] while they were both members of the Wood Players in White Plains, New York—the first stock company Tracy joined after graduating. The couple was engaged in May 1923,<ref>Curtis (2011) p. 12.</ref> and married on September 10 of that year between the matinee and evening performances of his show.<ref>Curtis (2011) pp. 14–15.</ref>

Their son, John Ten Broeck Tracy, was born in June 1924.<ref>Curtis (2011) p. 21.</ref> When John was 10 months old, Louise discovered that the boy was deaf.<ref>Curtis (2011) p. 78.</ref> She resisted telling Tracy for three months. Tracy was devastated by the news<ref>Curtis (2011) p. 84.</ref> and felt lifelong guilt over his son's deafness. He was convinced that John's hearing impairment was a punishment for his own sins.<ref>Curtis (2011) pp. 85, 95, 108, 112, 166, 338, 586, 647.</ref> As a result, Tracy had trouble connecting with his son<ref>Curtis (2011) pp. 96, 565.</ref> and distanced himself from his family. [[Joseph L. Mankiewicz]], a friend of Tracy's, later theorized: "[Tracy] didn't leave Louise. He left the scene of his guilt."<ref>Cutis (2011) p. 338.</ref> A second child, Louise "Susie" Treadwell Tracy, was born in July 1932.<ref>Curtis (2011) p. 177.</ref> The children were raised in their mother's [[Episcopal Church (United States)|Episcopal]] faith.<ref>Curtis (2011) p. 485.</ref>

Tracy left the family home in 1933,<ref>Curtis (2011) p. 205.</ref> and he and Louise openly discussed the separation with the media, maintaining that they were still friends and had not taken divorce action.<ref>Curtis (2011) pp. 206, 216, 226.</ref> From September 1933 to June 1934, Tracy had a public affair with [[Loretta Young]], his co-star in ''Man's Castle''.<ref>Curtis (2011), p. 210 for beginning of affair, p. 235 for break-up. For public nature of the relationship see pp. 213, 215.</ref> He reconciled with Louise in 1935.<ref>Curtis (2011) p. 253.</ref> There was never again an official separation between Tracy and his wife, but the marriage continued to be troubled.<ref>Curtis (2011) p. 319.</ref> Tracy increasingly lived in hotels and by the 1940s, the two were effectively living separate lives.<ref>Curtis (2011) p. 426.</ref> Tracy frequently engaged in extramarital affairs,<ref>Curtis (2011) p. 450, quotes [[Claire Trevor]] saying: "He did have quite a line of conquests. Women loved him." Similar quotations are given from Joseph L. Mankiewicz and Clark Gable.</ref> including with co-stars [[Joan Crawford]] in 1937<ref>Curtis (2011) p. 327.</ref> and [[Ingrid Bergman]] in 1941.<ref>Curtis (2011) p. 413.</ref> He had an affair with [[Myrna Loy]] in 1935 and 1936.<ref>Christopher Andersen, An Affair to Remember: The Remarkable Love Story of Katharine Hepburn and Spencer Tracy, William Morrow et Company, 1997, p.86.</ref><ref>Darwin Porter, Katharine the Great: A Lifetime of Secrets, 2004, p. 372.</ref><ref>Jane Ellen Wayne, The Leading Men of MGM, First Carroll and Graf, 2005, p.207.</ref> In 1990, during a phone interview with educator Alan Greenberg, Loy revealed she was in love with Tracy.
