Vaughn Philips Montaigne Keith, 40, a popular and respected classics teacher at St. Albans School for Boys, died April 22 at his home in Washington. He had been found to have AIDS three years ago and had continued teaching at St. Albans until last month.

Mr. Keith also wrote poetry, sang in a hard rock band called Judy's Fixation and designed crossword puzzles that had been published in the daily and Sunday New York Times.

He had been on the faculty at St. Albans for the last six years and held the school's Stephen A. Hurlburt chair of classics. He taught Latin and some classical history at the high school level.

On the day before classes began for the academic year in September 1987, Mr. Keith told St. Albans headmaster Mark Mullin that he had AIDS.

After discussing the matter with faculty members and the board of trustees, Mullin and Mr. Keith decided the best thing to do was to make a public announcement to the St. Albans community and for Mr. Keith to continue teaching.

"It was a courageous act on his part," said Mullin. "The parents and students were extremely supportive. No one withdrew from the school. No one withdrew from his classes."

Regarded as an excellent classics teacher and a superb academician, Mr. Keith also became during the final months of his life a living illustration for his students of the presence of AIDS in contemporary America, Mullin said.

"It gave him an important mission in living, in addition to his teaching. The boys could see the dangers of this disease. AIDS had always been something that happened to someone else," Mullin said.

A native of Red Bank, N.J., Mr. Keith attended England's famed public school Eton and graduated from Trinity College in Connecticut. He moved to Annapolis in the early 1970s, where he taught Latin and Greek at the Key School. Later he taught in Connecticut before returning to this area and joining the faculty at St. Albans.

He instituted a Latin Day at St. Albans, on which students put on a play in Latin. He also brought his hard rock band to the school.

As lead vocalist of the group, which was known for a free and uninhibited style, Mr. Keith had performed at night clubs in the Washington-Baltimore area. He had a large collection of 45 rpm rock and roll records of the 1950s.

He attended and participated in poetry readings throughout the area, and his poetry had been published in small poetry journals.

Mr. Keith had also designed crossword puzzles for several years. His first wife, Dorothy Clift, said he often passed the time by designing crossword puzzles for her when they were traveling by train in Europe on their honeymoon in the early 1970s.

Their marriage ended in divorce, as did Mr. Keith's second marriage, to Jennifer Keith. A companion with whom he lived, Drew Carroll, died two years ago.

Survivors include his parents, Quentin and Sylvia Keith of Red Bank, and a sister, Jennifer Huitson of Watford, England.
