WILLIAM CROOKES
WILLIAM CROOKES
BIRTH & DEATH DATE
JUNE 17, 1832 - APRIL 4, 1919
He was a german mechanical engineer and
physicist, who, on 8 november 1895, produced
and detected electromagnetic radiation in a
wavelenght range known as x-rays or
roentgen rays, an achivement that earned him
the inaugural nobel prize in physics in 1901.
WILHEM CONRAD ROENTGEN
He demonstrated the use of a radiographic
intensifying screen in 1896, but only many years later did it receive adequate recognition and use.
MICHAEL PUPIN
Wife of Wilhelm Conrad Roentgen, the
discoverer of X-rays, she was the first person
to experience the x-ray on her body on
December 22, 1895.

TELEPHONE LABORATORIES BELL
1946
The first Xray patient in February 1896
Eddie McCarthy
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.
Charles leonard
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.
Thomas Edison
He experienced a severe x-ray 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 an early victim of radiation
dermatitis and its complications.
CLARENCE DALLY
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.
William Rollins
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.
HC SNOOK
In 1913, 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.
WILLIAM COOLIDGE
In 1913, he invented the stationary grid
(“Glitterblende”); 2 months later, he applied
his second patent for a moving grid.
