Ted Dimon became a stockbroker at Shearson Hammill in 1953, initially as an assistant for his father, a year after his marriage to Themis Anastasia Kalos. Both were children of Greek immigrants. Themis, his wife of 65 years, also battled cancer and died just a day after her husband on June 6 at 84 years old. The elder Mr. Dimon, known for dressing sharply in striped shirts paired with a bold tie picked out by his wife many mornings, survived many of the mergers and acquisitions that washed over Wall Street. He eventually found himself working for financier Sandy Weill. Ted and Themis became close with Mr. Weill and his wife Joan, ultimately introducing Jamie to the former bank titan. Ted Dimon stayed on at what would become Citigroup for several years even after Jamie left in 1998. In 2006, Ted Dimon moved to Merrill Lynch, and in November 2009, at 78 years old, he joined the brokerage unit of J.P. Morgan with three other brokers, all women who have worked with him for more than 20 years. Ted and Themis Dimon are survived by Themis’s sister, Olga; their children Peter, Ted Jr. and his wife Tamara, James and his wife Judy; their grandchildren Julia and her husband Joey, Laura, Kara and her fiancé Conor; and their great grandchild Caroline.
