Henry Gwyn Jefferys Moseley was born in Weymouth, England, on November 23, 1887. He was born into a wealthy family which provided for his education that later was the basis of his outstanding scientific findings. He attended Trinity College, Oxford and graduated with high honors. After College he worked he laboratory of Ernest Rutherford at the University of Manchester. At first he worked with X-rays which later lead him to the conclusion that all elements had a clear progression of protons in the atomic nucleus. This changed the periodic table to what we now know of today. It is based on the order of the atomic numbers instead of its weight like it did before his discovery. He finally died in battle during WWI on August 10, 1915.
