Henry Loomis was born in 1919 Tuxedo Park , New York. His father was Alfred Lee Loomis , a rich New York City businessman .In 1940, Henry Loomis dropped out of Harvard University to join the United States Navy .He was able to put to good use his knowledge of radar technology that he had learned about because of his father’s work .After graduating at the top in his naval(海军的) training class, Henry Loomis became a teacher at the Navy's radar training school in Hawaii. By the end of World War Two, Henry Loomis had received many honors for his service, including a Bronze Star and an Air Medal. He left the Navy in 1946 to begin graduate(研究生)studies.

Henry Loomis later moved to Washington, D.C. to begin another part of his career in public service. He held positions in the Department of Defense and other agencies: In 1958, he became director of the Voice of America.

During his travels around the world, Mr. Loomis saw that English was becoming an

important international language. He believed that it was important to make English easier to

understand by listeners of VOA broadcasts whose native language was not English. So Mr. Loomis asked VOA program manager Barry Zorthian to develop a way to broadcast to listeners

with a limited knowledge of English:

The result of this effort was Special English: The first Voice of America broadcast in Special English took place on October 19th, 1959. Those against his ideas at the time said the Special English method of broadcasting at a slower rate with a limited vocabulary would never work, it was not practical. American embassies(大使馆) demanded that the program be called off. But Mr. Loomis supported the program.

Soon, VOA began to receive hundreds of letters from listeners praising the program. Special English programs became some of the most popular on VOA. We are pleased to say that our programs still are.
