William Herbert Rollins (June 19, 1852 - 1929) was an American scientist, inventor, and dentist. He was a pioneer in radiation protection.Many of his inventions and investigations in medical radiography and photography have been ranked in importance with those of Thomas A. Edison, Elihu Thomson, and William J. Morton.
Unprotected experiments in the U.S. in 1896 with an early X-ray tube (Crookes tube), when the dangers of radiation were largely unknown.[1]The history of radiation protection begins at the turn of the 19th and 20th centuries with the realization that ionizing radiation from natural and artificial sources can have harmful effects on living organisms.
Modifications were made to Finsen's original design, and it found its most common forms in the Finsen-Reyn lamp and Finsen-Lomholt lamp. By 1905, it was estimated that fully 50 percent of the cases of lupus were successfully healed by Finsen's methods. [15] Finsen was soon awarded a Nobel Prize for his research.

Many inventions improved the quality of radio, and amateurs experimented with uses of radio, thus planting the first seeds of broadcasting.

Research done in the fields of astronomy, alchemy, and meteorology by Tycho and his assistants produces high precision measurements of the planets. 1595 – The microscope is invented in the Netherlands. 1608 – Evidence of the earliest known telescope appears in the Netherlands, when a patent is submitted by Hans Lipperhey.

Isidor Isaac Rabi won the Nobel Prize in Physics in 1944 for his discovery of nuclear magnetic resonance, which is used in magnetic resonance imaging.In 1950, spin echoes and free induction decay were first detected by Erwin Hahn [5] [6] and in 1952, Herman Carr produced a one-dimensional NMR spectrum as reported in his Harvard PhD thesis.
