Stephen Heidrich, a retired interior designer, died at home on Oyster Shores Road in East Hampton on May 14 after a short illness. He was 94.
Mr. Heidrich was born on March 23, 1918, in New Haven, Conn., to Stephen Heidrich Sr. and the former Beulah Chabot. His schooling included a scholarship to Pratt Institute in New York City, where he studied design. He also studied commercial science at New York University.
Though he worked for a time on Wall Street at Bankers Trust, he returned to design and was associated with Alfons Bach, who was a furniture designer, and the interior decorator Dorothy Draper.
He then formed an partnership with Kim Hoffman and was active in the field for 30 years. The firm of Kim Hoffman and Stephen Heidrich Interior Design worked on residences, showrooms, stores, and offices and were consultants or design editors for several publications in the United States, France, and England. During the partnership, Mr. Heidrich managed the building they owned, on East 73rd Street in Manhattan.
During his career, he received the Pierre Saint-Gaudens Medal for fine draftsmanship. He was a member of the American Designers Institute.
Between 1961 and 1971, he modeled for the Rice McHugh agency.
He retired in 1983 when he was 63, planning to live full time in East Hampton in a house shared with his longtime companion, Ray Tomkin. They had designed the house together in 1968, and it became their permanent residence in 1985.
Prior to his retirement, the couple traveled widely and saw many parts of the world, Mr. Tomkin said.
Together for 52 years — and each a fraternal twin — Mr. Heidrich and Mr. Tomkin became domestic partners on Sept. 16, 2003, and married on Aug. 1, 2011, when it became legal for them to do so in the State of New York.
In addition to Mr. Tomkin, he is survived by a niece, Jean Wilson of Carmel, N.Y., to whom he was close, and a nephew, Bruce Clifford of Anchorage, Alaska. His sister, Lielah, died before him.
As was Mr. Heidrich’s wish, there was no funeral or memorial. He was cremated on May 17.
Donations in his memory have been suggested to East End Hospice, which provided generously for his home health care during his illness, Mr. Tomkin said. The organization accepts contributions by mail at P.O. Box 1048, Westhampton Beach 11978.
