Van De Graaff

  1. 1. December 20, 1901 to January 16, 1967
  2. 2. Robert Van de Graaff’s greatest achievement was The Van de Graaff Generator which he finished on Nov. 28, 1993 and produced 7,000,000 volts. “ Man Hurls Bolt of 7,000,000 Volts” was the New York Times reporter said when the machine was publicized.
  3. 3.  Van de Graaff was born in Tuscaloosa, Alabama.  He and his brothers loved playing football.  Van de Graaf came from a line of lawyers, however Van de Graaff “was destined to be different.”  The Van de Graaff family was known as community moves and shakers.  Van de Graaff married Catherine Boyden in 1936 and they had two sons named John and William.
  4. 4. In 1913, Robert Van de Graaff played a football game against Tennessee and nearly lost his ear. He literally grabbed his ear and tried to yank it from his head. However, his teammates stopped him and he was bandaged. He wanted to keep playing so he was willing to tear off his ear, which shows an insane amount of dedication that carried over to Van De Graaff’s study and love of science.
  5. 5.  Van de Graaff studied at the University of Alabama where he got his Bachelors of Science in 1922, and his Masters of Science in 1923.  He obtained his P.H.D. at Queen’s College.  He also went to Princeton as a National Research Fellow and also studied at Harvard Medical School.
  6. 6.  Van de Graaff created the Van de Graaf generator
  7. 7.  He also used X rays for treating cancerous tumors with precisely penetrating radiation and this was first used clinically in 1937.  He also was the director of the High Voltage Radiographic Project during World War II. He directed the adaptation of the electrostatic generator to precision radiographic examination of the U.S. Navy ordnance.  He also invented the insulating core transformer, also a project involving voltage.
  8. 8. Van de Graaff received a Rockefeller Foundation grant during World War II for his help and he also got the privilege of naming an invention after him (his generator). He also created the High Voltage Engineering Corporation (HVEC).
  9. 9.  http://www.nnp.org/nni/Publications/Dutch- American/vandegraaf.html  http://www.mos.org/sln/toe/history.html  http://tvdg10.phy.bnl.gov/vandegraaff.html This is a generator like the Van de Graaff, it just has less voltage.
