Dr. Louis Ormont, pioneer in group psychotherapy; 90

KEENE, N.H. - Dr. Louis Ormont, a pioneer in the field of group psychotherapy, died Saturday at Cheshire Medical Center in Keene, where he was recuperating following open heart surgery in July. He was 90.

Dr. Ormont developed a practice of seeing people only in group treatment, and he trained hundreds of therapists.

In 1989, 72 of his colleagues founded, in his honor, The Center for Group Studies, a New York educational institution that teaches group-leadership skills.

Dr. Ormont authored more than 30 articles and books, and also taught at the Boston Graduate School of Psychoanalysis.

A memorial service will be held in January in New York City.

He leaves his wife, Marian Joan (Connor) of New York City; a son, Michael Llewellyn of Keene; a daughter, Marian Amanda of Devon, Pa.; a brother, Joseph of Philadelphia; and five grandchildren.
