He is an American engineer and physcial chemist. William's helped improve Tungsten filaments which helped to develop modern light bulbs and the X-Ray Tube. He then joined the General Electric Research Laboratory.
William D. Coolidge was an American engineer and a chemist who developed the incandescent lamp bulb and the X-ray tube. He also helped with the Tungsten filaments.
Willaim D. Collidge was an engineer and he was also a physical chemist. His improvements with the Tungsten filaments was very essential in the develpoment of the modern light bulb. And also the X-Ray Tube. Thats who Willaim D. Collidge is!
he was an engineer and chemist. He was the person that made the xrey machines. He was a pretty smart guy. He was a cool man that made a lot of great findings and did a lot of cool things.
He was an Amercan chemist and engineer. William helped imporove the light bulb and he also helped make the X-ray. He then went on to Join General Eletric Research Laboratory. He was very smart.
William D. Coolidge was an enginer and physical chemist. He made a ductile tungsten (a pliable metal)which is put in lightbulbs. This made better quality bulbs. THen he used it for X-ray tubes. So now X-rays worked better and safer.
He is a famous engineer and physical chemist. He was from America and was in the General Electric Research Labratory. He helped develop modern day things such as light bulbs and X-ray machines.
He was a american enginner and a chemist. He came up and helped people with their inventions, like the Tungsten filaments and the x ray tube. He was the greatest person that ever lived on the face of the earth.
