Curtis Grubb (c.1730—1789), Patriot and oldest son of Peter and Martha Bates Grubb, was a second-generation member of the Grubb Family Iron Dynasty along with his younger brother Peter Jr. The brothers operated the Cornwall Ironworks, making significant contributions to the American Revolutionary War effort, and Curtis served several terms in the Pennsylvania Provincial Assembly. He was also one of the largest enslavers in Pennsylvania at the time of independence, registering twenty-five people as his property in 1780 in accordance with state gradual abolition law.
