Among the titles the company published was Sisters, the blockbuster 1994 collaboration of essayist Carol Saline with Wohlmuth, a former Inquirer photographer. The coffee-table book spent 63 weeks on the New York Times bestseller list.
Wohlmuth and Saline collaborated on two other books, Mothers & Daughters and Best Friends, published by Doubleday.
Mr. Teacher was very supportive of her book projects, Wohlmuth said, even when they required her to be away from home for long periods.
"Go for it," he would tell her.
After three decades of operation, Running Press was acquired by the New York independent publishing company Perseus Books Group in 2002. Mr. Teacher shifted gears and became an artist, though his brother stayed with the company.
"He would sit in the kitchen and listen to French cafe music and paint," his wife said. His paintings were exhibited at the Jersey Shore, and some sold, she said.
Mr. Teacher loved Maine coon cats, sailing, fly-fishing, delivering jokes with perfect timing, mentoring his nieces and nephews, and brainstorming for ideas that often led to books or creative projects.
"He was very caring, he loved to help people, and he was interested in other people's lives and their stories," his wife said. "He was a very good listener."
Mr. Teacher graduated from Abington Senior High School and American University. He had friends worldwide.
Surviving, in addition to his wife and brother, are a daughter, Rachael Teacher; a stepson, Michael Parker; sisters Melissa Cookman and Amy Hudak; a grandson; and many nieces and nephews.
He was previously married to the former Marilyn Parker. They divorced. She died in 2011.
The funeral will be at 2 p.m. Thursday, March 27, at Congregation Keneseth Israel, Old York and Township Line Roads, Elkins Park. Interment will be in Montefiore Cemetery in Jenkintown. The family will sit shiva at Mr. Teacher's home.
