Interior of A.P. Green Company, around 1955

The family business continued with Robert Stafford Green, one of A. P.’s sons, assuming the presidential duties for the next four years. The first non-family member joined the board of directors in 1950 when William S. Lowe was named president. Though the family held a majority on the board that first decade after Green’s retirement, they gradually began offering stock to the public. The family’s majority on the board ended in 1966. That same year shares of A. P. Green were traded on the New York Stock Exchange, opening the door for U.S. Gypsum to acquire the company in 1967. The company is currently part of ANH Refractories Company.
