Benjamin Sonnenberg (July 12, 1901 – September 6, 1978) was a Belarusian-born American public relations consultant who represented celebrities and major corporations. He was best known for the lavish entertaining he hosted for clients and other notables at his Manhattan townhouse located at 19 Gramercy Park South.
Sonnenberg was born in Brest-Litovsk, Russia, now part of Belarus. He began his life living in poverty in a small wooden hut. Because of this poverty, his family emigrated to the United States with his family in 1910 to Lower East Side, Manhattan, New York City. Sonnenberg attended Public School No.62 and then DeWitt Clinton High School. He took part in drama and dance at Henry Street Settlement, where his mother was a cleaning lady. Miss Wald, the director, was very impressed with Ben. At the age of 16, she offered him a job as the leader of the boy's club, and in turn allowed him to continue his schooling and live at the settlement house. Two years later, Miss Wald helped him get a scholarship to study at Columbia College. He got a job covering Columbia University sports for the Brooklyn Eagle. This helped his writing skills to become a publicist.
He married Hilda Kaplan in March 1924. Brendan Gill, a close friend of Sonnenberg claimed, "Ben wanted to be remembered as he was in his prime." His will was written on December 7, 1977 after he learned he was terminally ill with throat cancer. The will directed his executors of this estate to destroy all his files and papers. On September 5, 1978 Sonnenberg died in New York City at age 77 of a heart attack on September 6, 1978.
Sonnenberg was unsatisfied by the challenge of college and answered an ad in The New York Times with the Chicago Portrait Company as a door-to-door salesman. He became bored and quit after two months. Then, he hitchhiked to Flint, Michigan where he worked as a reporter and movie critic for the Flint Journal. He returned to New York City in 1921.
