Florence Snyder, a music teacher who had been a concert pianist under her maiden name, Elaine Frantz, died Tuesday at Sinai Hospital of congestive heart failure. She was 85.

Services for Mrs. Snyder, a resident of the Highfield House Condominium on North Charles Street, were being held today at Sol Levinson & Bros. funeral establishment, 6010 Reisterstown Road.

Her first husband, Louis Vennett, died about 40 years ago. Her second husband, Dr. Nathan Snyder, died about 20 years ago.

She taught piano at the Peabody Conservatory of Music in the 1950s and continued to teach students privately at her home until her final illness. Earlier, she taught at the Curtis Institute of Music and Temple University in Philadelphia and at the Mannes School of Music in New York.

The Baltimore native won piano scholarships to the Peabody Conservatory and later to the Curtis Institute.

Her survivors include a niece, a nephew and several cousins.

The family suggested memorial contributions to the Leonard Frantz Memorial Fund, in care of the Alumni Office of the Curtis Institute. It honors her late brother, who also was a musician.
