Question: The creator of the Cincinnati Musical Center half dollar is also the creator of what other coin? 
Context: 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. The Connecticut Tercentenary half dollar, sometimes called the Connecticut half dollar, is a commemorative fifty-cent piece struck by the United States Bureau of the Mint in 1935.  The coin was designed by Henry Kreis, and commemorates the 300th anniversary of the founding of Connecticut.  Its obverse depicts the Charter Oak, where according to legend, Connecticut's charter was hidden to save it from the English; an eagle appears on the coin's reverse side. The Alabama Centennial half dollar, or Alabama half dollar, was a commemorative fifty-cent coin struck by the United States Bureau of the Mint in 1921 as a belated acknowledgement of the 100th anniversary of Alabama's admission to the Union in 1819.  The coin was created by Laura Gardin Fraser, who became the first woman designer of a coin. The Columbian half dollar is a coin issued by the Bureau of the Mint in 1892 and 1893.  The first United States commemorative coin, it was issued both to raise funds for the 1893 World's Columbian Exposition and to mark the quadricentennial of the first voyage to the Americas of Christopher Columbus, whose portrait it bears.  The Columbian half dollar was the first American coin to depict a historical person. The Rhode Island Tercentenary half dollar, sometimes called the Providence, Rhode Island Tercentenary half dollar is a commemorative fifty-cent piece struck by the United States Bureau of the Mint in 1936.  The coin was designed by John Howard Benson and Arthur Graham Carey.  Its obverse depicts Roger Williams, founder of Rhode Island.  Although intended to honor the 300th anniversary of the state capital, Providence, no mention of the city appears on the coin. The dollar coin is a United States coin worth one United States dollar.  It is the third largest American coin currently minted in terms of physical size, with a diameter of 1.043 inches (26.5 mm) and a thickness of .079 inches (2 mm), coming second to the half dollar.  Dollar coins have been minted in the United States in gold, silver, and base metal versions.  Dollar coins were first minted in the United States in 1794.  The term silver dollar is often used for any large white metal coin issued by the United States with a face value of one dollar, whether or not it contains some of that metal.  While true gold dollars are no longer minted, the Sacagawea and Presidential dollars are sometimes referred to as golden dollars due to their color. Thomas Gatch Melish (October 28, 1876 – February 15, 1948) was a Cincinnati entrepreneur and coin collector.  In the 1930s, Melish was responsible for two United States commemorative coin issues, the Cincinnati Musical Center half dollar and the Cleveland Centennial half dollar. The Vermont Sesquicentennial half dollar, sometimes called the Bennington–Vermont half dollar or the Battle of Bennington Sesquicentennial half dollar, is a commemorative fifty-cent piece struck by the United States Bureau of the Mint in 1927.

The current coin, the Kennedy half dollar, depicts the profile of President John F. Kennedy on the obverse and the Seal of the President of the United States on the reverse, but the design has undergone a number of changes throughout its history.
