Katherine Louise Tucker '94, a member of the Harvard-Radcliffe Collegium Musicum and a former resident of Dunster House, took her own life Monday after suffering from depression, family members said yesterday.

Tucker, 23, graduated from the College last year and had remained in the Boston area to study voice lessons and sing with the Collegium, an activity in which she participated throughout her undergraduate years, according to her brother-in-law Gregory W. Tucker-Kellogg.

Members of the Collegium Musicum declined to comment yesterday on Tucker, but her family said Tucker, who sang as a soprano and alto during her undergraduate career, had so enjoyed performing with the group that she continued to do so despite having graduated.

"Music and math were her two favorite things," Tucker-Kellogg said.

Tucker, who concentrated in applied mathematics and also performed in the Dunster Opera Society, graduated from Ward Melville High School, in Setauket, NY. She is survived by her father Alan C. Tucker '65, her mother Amanda Z. Tucker and her sister Lisa Tucker-Kellogg.

A memorial service is scheduled for Saturday at 3:45 p.m. at the Friend's Society of Cambridge, at 5 Longfellow Park. Members of the Collegium Musicum will be performing at the service.

The family requested that in lieu of flowers of donations be made to the Harvard Radcliffe Collegium Musicum.
