The film showed that in late August 1939, Nazis posing as Polish citizens attacked a radio station in Gleiwitz because it was near the Polish border in order to strengthen the Nazi argument for the Sept. 1, 1939, invasion that touched off World War II.
Mr. Pick made a living in Shanghai during World War II in part by cleaning apartments before arriving in Philadelphia in 1948.
His twin sister, Ruth Tengood, had also escaped Nazi Germany, and he joined her in Philadelphia in a European Jewish neighborhood bounded by Seventh and Eighth, Girard, and Poplar Streets, his son said.
The neighborhood constituted one block of North Marshall Street.
"It was a little European town," his son said, "with the synagogue in the middle of the block."
Mr. Pick worked as a short order cook at the Germantown Cricket Club before becoming a druggist at Hausmann's Pharmacy at Sixth and Girard Streets from 1949 to 1990.
"Hausmann's imported herbs" for medicinal purposes, his son said, "and he ran that part of the business."
The twins' parents died in the Holocaust, he said.
In addition to his son and sister, Mr. Pick is survived by a daughter, Dr. Diane Dickerman; five grandchildren; and a great-grandson. His wife, Ella, died in 2011.
The funeral was set for noon Sunday, Sept. 1, at the Roosevelt Memorial Park Mausoleum, Old Lincoln Highway in Trevose.
