In 1925, Paul, with the support of his father Julius, who was the first Feiss partner at Joseph & Feiss, engineered the ouster of his brother Richard Feiss. The two believed that Richard's progressive programs were too expensive and not cost effective. Prior to this time, Paul had been more interested in philanthropy than in business. He founded, or helped to found, a number of Cleveland's best known institutions, including the Cleveland Museum of Art (1916), Mt. Sinai Hospital on East 105th Street (1916), and the Cleveland Orchestra (1919). After ousting his brother from Joseph & Feiss, he turned his attention to business, assuming the duties of general manager (1925), vice-president (1927), president (1930), and then chairman of the board (1937), a position he held until his death.
