The Cincinnati Musical Center half dollar or Cincinnati Music Center half dollar is a commemorative 50-cent piece struck by the United States Bureau of the Mint in 1936.
 Produced with the stated purpose of commemorating the fiftieth anniversary of Cincinnati, Ohio as a center of music, it was conceived by Thomas G. Melish, a coin enthusiast who controlled the group which was allowed to buy the entire issue from the government, and who resold the pieces at high prices.
Constance Ortmayer (July 19, 1902 – May 15, 1988) was an American artist well known for designing the 1936 Cincinnati Musical Center half dollar.
 Ortmayer was inspired to become an artist by her father, Rudolph Ortmayer, who worked as a lithographer.
 In 1926, Ortmayer began studying under Austrian born sculptor Franz Plunder.
 She graduated from the Royal Academy in Vienna, Austria and studied Master School of the Royal Academy.
 Upon returning to the United States in 1932, Ortmayer found difficulty gaining employment.
 With the assistance of her friend, a tutor of Treasury secretary Henry Morgenthau, Jr. Ortmayer became employed with the Section of Painting and Sculpture, coordinating design contests for federal buildings.
 In 1937, she ended her employment with the Section.
 Soon after, she was recruited as a sculpture instructor at Rollins College in Winter Park, Florida by the current president, Hamilton Holt.
 Ortmayer was awarded commissions to design and create two bas reliefs for post offices in Arcadia, Florida and Scottsboro, Alabama as a result of her entering a national design competition.
 The Arcadia relief, completed in 1939, is titled "Arcadia".
 It features five people (two men, a woman and two children) with a cow and her calf.
 The second relief, completed in 1940, is titled "Alabama Agriculture".
 It features three separate panels, each depicting different stages of crop harvest.
 In 1941, Ortmayer was promoted to assistant professor of sculpture in 1941.
 In 1945, she was further promoted to associate professor.
 She reached the status of professor of sculpture in 1947.
 During her career at Rollins, Ortmayer created a number of award–winning medals.
 Ortmayer retired in 1968.
 She died on May 15, 1988.
