RT 102 (Inventor)

Question 1

Wilhelm Conrad Roentgen

Answer 1

• (March 27 1845-February 10 1923
  He was a German Mechanical Engineer and Physicist. Who, on November 8, 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or Roentgen rays, an achievement that earned him the inaugural Nobel Prize in physics in 1907.

Question 2

Anna Bertha Ludwig
(

Answer 2

-April 22, 1839- October 31, 1919)
Wife of Wilhelm Conrad Roentgen, the discoverer or x-rays. She was the first person to experience the x-ray on her body on December 22, 1895.

Question 3

William Crookes

Answer 3

• (June 17, 1832-April 4, 1919)
  He was a British Chemist and Physicist who attended the Royal College of Chemistry, now part of Imperial College London, and worked on Spectroscopy. He was a pioneer of Vacuum Tubes, inventing the Crookes Tube which was made in 1875.

Question 4

Michael Pupin

Answer 4

-(October 9, 1854- March 12, 1935)
He demonstrated the use of a Radiographic Intensifying Screen in 1896. But only many years later did it receive adequate recognition and use.

Question 5

Charles Leonard

Answer 5

-September 16, 1822- August 27, 1918)

He found that by exposing Two Glass X-Ray Plates with the emulsion surfaces together, exposure time was halved, and the image was considerably enhanced.

Question 6

Thomas Edison

Answer 6

-(February 11, 1847-October 18, 1931)
He developed the Fluoroscope in 1898. He was an American Inventor and Businessman. He developed many devices in fields such as Electric Power Generator, Mass Communication, Sound Recording, and Motion Pictures.

Question 7

Clarence Dally

Answer 7

-(January 8, 1865-October 2, 1904)
He experienced a severe xray burn that eventually required amputation of both arms. He was an American Glassblower, noted as an assistant to Thomas Edison in his work on X-rays and as early victim of Radiation Dermatitis and its complications.

Question 8

William Rollins

Answer 8

-(June 19, 1852-1929)
Before 20th century Boston dentist William Rollins used x-rays to image a Teeth and found that restricting the x-ray beam with a sheet of lead and with a hole in a center, a diaphragm, and inserting a leather or aluminum filter improved the diagnostic quality of radiographs.

Question 9

Homer Clyde Snook

Answer 9

-(March 25, 1878-September 23, 1942)
In 1907, he introduced a Substitute High-Voltage Power Supply, an interruptless transformer. It was not until the introduction of Coolidge Tube that the Snook Transformer was widely adopted.

Question 10

William Coolidge

Answer 10

-October 23, 1873-February 3, 1975)
In 1973, he unveiled his hot-cathode x-ray tube to the medical community. It was immediately recognized as far superior to the Crookes Tube. It was a vacuum tube that allowed x-ray intensity and energy to be selected separately and with great accuracy. X-ray tubes in use today are refinements of the Coolidge Tube.

Question 11

Gustav Bucky

Answer 11

-September 3, 1880-February 19, 1963)
In 1913, he invented the stationary grid “glitterblinde”; 2 months later, he applied his second patient for a moving grid.

Question 12

Hollis Potter

Answer 12

-February 16, 1880- October 15, 1964)
In 1915, he probably unaware of Bucky’s patent because of WWI, also invented a moving grid. To his credit, Potter recognized Bucky’s work and the Potter-Bucky grid was introduced in 1921.
