In early editions of Thursday's Washington Post, an obituary about Alexis Tcherkassky, 76, who died Monday following a stroke, failed to mention one of his two daughters. She is Marianna Tcherkassky Orr of New York City, a principal dancer with the American Ballet Theater.

Alexis Tcherkassky, 76, a retired senior editor with the Voice of America who had been an opera singer and manager of the American Ballet Theatre, died Monday at Suburban Hospital in Bethesda after a stroke.

Mr. Tcherkassky was born in St. Petersburg, now Leningrad, Russia. He attended schools there and in Shanghai and Paris. During his career as an opera singer, he performed on European and American stages.

Having moved to New York City in 1932, Mr. Tcherkassky left the opera to become manager of the American Ballet Theatre, a post he held through the 1940s and early 1950s.

In 1952, he moved to the Washington area and joined the Russian language division of the Voice of America, where he served as a writer, announcer and senior editor. Mr. Tcherkassky wrote and directed "Performing Arts Briefs," a program that focused on items of cultural interest. He retired in 1974.

Survivors include his wife, Lillian, of Kensington; two daughters, Lisa, of Kensington, and Marianna, of New York City; a son, Michael, of Columbia, Md., and two grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the St. Nicholas Russian Orthodox Church, 3500 Massachusetts Ave. NW, Washington, D.C.
