Charles Hershman, who with his wife founded Sharon Country Day Camp in 1963 and was known to generations of campers as “Uncle Charlie,” died Jan. 30. He was 87. In an interview, his son, Stuart Hershman, who operates the camp with two siblings, said many former campers attended a celebration of his life. Every day during the summer season, he would greet campers as they arrived and wave goodbye as they left, his son said. Under Mr. Hershman’s direction, the camp gave “camperships” to children who could not afford to attend. “I think the big thing that the camp was known for was the relationship that campers had with other kids,” his son said. The camp is located in Walpole, near the Sharon line, and welcomes participants from surrounding communities. Mr. Hershman, who lived in Sharon, was involved in the town and was the first president of the Sharon High School booster club, his son said.
