Opera Singer, Self-Help Pioneer. A soprano, she followed a successful Broadway and operatic career with an even more successful one as a speech teacher for the rich and famous. Raised in a well-off Brooklyn family, Dorothy graduated from Cornell University with a degree in English in 1935 and while there discovered her musical talent by singing in the Glee Club. After vocal training in France she returned to America and sang with the NBC Symphony and the St. Louis Municipal Opera. In 1939 she was Miss Pinkerton in the world premiere of Gian Carlo Menotti's radio opera "The Old Man and the Thief"; after reaching the finals of the Metropolitan Opera Auditions of the Air, she appeared on Broadway in around 500 performances of "Rosalinda", an English version of Strauss' "Die Fledermaus". Dorothy performed with the Philadelphia Opera and the New York City Opera, singing Marguerite in Gounod's "Faust", Mimi from Puccini's "La Boheme", Micaela in Bizet's "Carmen", and the title heroine of Puccini's "Tosca". In 1951 Dorothy was Lady Thiang in the world premiere of "The King and I", introducing the song "Something Wonderful", and later performed on Broadway in "My Darling Aida", an adaptation of Verdi's work which essentially flopped. Her second marriage, to advertising executive Milton Raymond in 1957, was to lead to her later calling....noting that magazines were teaching women to look good but not to speak well, she remembered a technique of tightening the abdominal muscles to control stage fright that she had learned from Yul Brynner and founded Speech Cosmetics, later called Speech Dynamics, in the mid 1960s. She published "Speech Can Change Your Life" (1970), "Make the Most of Your Best" (1981), and "Never Be Nervous Again" (1987) and while her client list was mostly anonymous it is known to have included President Carter, Bob Dole, and Menachem Begin. She was often quoted as saying "I don't teach smile, I teach animation". Dorothy lived out her days in Manhattan and died of the infirmities of age; her date of birth is sometimes given as 1917 or 1919 but most sources list the earlier date.
