Hoagland Howard "Hoagy" Carmichael (November 22, 1899 - December 27, 1981) was an American composer, pianist, singer, actor, and bandleader. American composer and author Alec Wilder described Carmichael as the "most talented, inventive, sophisticated and jazz-oriented of all the great craftsmen" of pop songs in the first half of the twentieth century. Carmichael was one of the most successful Tin Pan Alley songwriters of the 1930s, and was among the first singer-songwriters in the age of mass media to utilize new communication technologies, such as television and the use of electronic microphones and sound recordings. Carmichael composed several hundred songs, including fifty that achieved hit record status.
Carmichael died of heart failure at the Eisenhower Medical Center in Rancho Mirage, California, on December 27, 1981, at the age of 82. His remains are buried in Rose Hill Cemetery in Bloomington, Indiana. In 1986 Carmichael's family donated his archives, piano, and memorabilia to his alma mater, Indiana University, which established a Hoagy Carmichael Collection in its Archives of Traditional Music and the Hoagy Carmichael Room to permanently display selections from the collection. Carmichael is considered to be among the most successful of the Tin Pan Alley songwriters of the 1930s, and was among the first singer-songwriters in the age of mass media to exploit new communication technologies, such as television and the use of electronic microphones and sound recordings. American composer and author Alec Wilder described Carmichael as the "most talented, inventive, sophisticated and jazz-oriented of all the great craftsmen" of pop songs in the first half of the 20th century. Carmichael was an industry trailblazer, who recorded varied interpretations of his own songs and provided material for many other musicians to interpret. His creative work includes several hundred compositions, some of them enduring classics, as well as numerous sound recordings and appearances on radio and television and in motion pictures. Music historian Ivan Raykoff described Carmichael as "one of America's most prolific songwriters" and an "iconic pianist" whose work appeared in more than a dozen Hollywood films, including his performances in classic films such as To Have and To Have Not and The Best Years of Our Lives. Among the hundreds of Carmichael's published songs, "Stardust" is one of the most frequently recorded. Carmichael's greatest strength was as a melodist, but he also became known as an "experimental" and "innovative" songwriter, whose "catchy, often jazz-infused, melodies" and "nostalgic, down-home lyrics" were memorable and had wide public appeal, especially with mass media promotion and through the efforts of numerous entertainers who performed his songs.

What was the legacy about?

Carmichael is considered to be among the most successful of the Tin Pan Alley songwriters of the 1930s, and was among the first singer-songwriters in the age of mass media

Sir Julian Sorell Huxley FRS (22 June 1887 - 14 February 1975) was a British evolutionary biologist, eugenicist, and internationalist. He was a proponent of natural selection, and a leading figure in the mid-twentieth century modern synthesis. He was secretary of the Zoological Society of London (1935-1942), the first Director of UNESCO, a founding member of the World Wildlife Fund and the first President of the British Humanist Association. Huxley was well known for his presentation of science in books and articles, and on radio and television.
As the 1930s started, Huxley travelled widely and took part in a variety of activities which were partly scientific and partly political. In 1931 Huxley visited the USSR at the invitation of Intourist, where initially he admired the results of social and economic planning on a large scale. Later, back in the United Kingdom, he became a founding member of the think tank Political and Economic Planning. In the 1930s Huxley visited Kenya and other East African countries to see the conservation work, including the creation of national parks, which was happening in the few areas that remained uninhabited due to malaria. From 1933 to 1938 he was a member of the committee for Lord Hailey's Africa Survey. In 1935 Huxley was appointed secretary to the Zoological Society of London, and spent much of the next seven years running the society and its zoological gardens, the London Zoo and Whipsnade Park, alongside his writing and research. The previous Director, Peter Chalmers Mitchell, had been in post for many years, and had skillfully avoided conflict with the Fellows and Council. Things were rather different when Huxley arrived. Huxley was not a skilled administrator; his wife said "He was impatient... and lacked tact". He instituted a number of changes and innovations, more than some approved of. For example, Huxley introduced a whole range of ideas designed to make the Zoo child-friendly. Today, this would pass without comment; but then it was more controversial. He fenced off the Fellows' Lawn to establish Pets Corner; he appointed new assistant curators, encouraging them to talk to children; he initiated the Zoo Magazine. Fellows and their guests had the privilege of free entry on Sundays, a closed day to the general public. Today, that would be unthinkable, and Sundays are now open to the public. Huxley's mild suggestion (that the guests should pay) encroached on territory the Fellows thought was theirs by right. In 1941 Huxley was invited to the United States on a lecturing tour, and generated some controversy by saying that he thought the United States should join World War II: a few weeks later came the attack on Pearl Harbor. When the US joined the war, he found it difficult to get a passage back to the UK, and his lecture tour was extended. The Council of the Zoological Society--"a curious assemblage... of wealthy amateurs, self-perpetuating and autocratic"--uneasy with their secretary, used this as an opportunity to remove him. This they did by abolishing his post "to save expenses". Since Huxley had taken a half-salary cut at the start of the war, and no salary at all whilst he was in America, the Council's action was widely read as a personal attack on Huxley. A public controversy ensued, but eventually the Council got its way. In 1943 he was asked by the British government to join the Colonial Commission on Higher Education. The Commission's remit was to survey the West African Commonwealth countries for suitable locations for the creation of universities. There he acquired a disease, went down with hepatitis, and had a serious mental breakdown. He was completely disabled, treated with ECT, and took a full year to recover. He was 55.

What activities did he pursue?
he became a founding member of the think tank Political and Economic Planning.
