After graduating with a bachelor’s degree in art education from Ohio State University, she married her former high school classmate, Richard Singer.

When her husband, a rabbi, decided to leave the rabbinate to study at the C.G. Jung Institute in Zurich, she and their daughter went along. Once there, she decided to also take courses.

Something clicked and she completed the training, receiving her diploma in analytical psychology from the institute. She went on to develop practices in Chicago; Duluth, Minn.; and California as a Jungian analyst, lecture at many international conferences and write numerous books on the subject.

“It just seemed to speak to her and to have resolution for her,” said her sister, Suzanne Kent.

Dr. Singer, 85, founding member of the C.G. Jung Institute of Chicago, died of a spontaneous cerebral hemorrhage, Thursday, Jan. 29, in her home in Beachwood, Ohio.

After living in different parts of the country, the Singers settled in the Chicago area in the 1960s, and Dr. Singer began studying for a doctorate in psychology at Northwestern University. Mr. Singer died in 1967, the year before she received her degree.

“When she became an Jungian analyst, she was the only one in the Chicago metropolitan area for many years,” said Jacqueline Mattfeld, the Jung Institute’s executive director. “She began a study group and would bring in lecturers and visiting analysts. She had a lot to do with Jung psychology being made known in the greater Chicago area.”

That group, the Analytical Study Club, joined in 1984 with the Chicago Society of Jungian Analysts to form the C.G. Jung Institute of Chicago.

“She was one of the most forward-thinking, vital people you can imagine meeting,” said Mattfeld. “She was highly articulate in speech and writing, with a great sense of humor. A woman of passion and ideas. She was one of the big woman names in Jungian thought.”

Her books include the “Boundaries of the Soul: The Practice of Jung’s Psychology”; “Modern Woman in Search of Soul”; and “The Power of Love.”

Dr. Singer later moved to California and joined the Jungian institute in San Francisco.

On New Year’s Eve more than 17 years ago, she attended a party with her sister in their hometown of Cleveland. Across the room was Dr. Irving Sunshine, a widower. The two fell in love and married in 1987. They returned to California and about seven years ago retired to their native Ohio.

In recent years, she returned to the art she had pursued as a young woman, joining a group of friends for weekly painting sessions of portraits and outdoor scenes.

Her daughter, Judith, died in 1970.

Besides her husband and sister, she is survived by her stepsons, Jonathan and Carl Sunshine; and five grandchildren.

A memorial service will be held Sunday in Cleveland. Plans for a service and reception at the C.G. Jung Institute of Chicago are pending.
