Apr. 20, 1928 British astronomer Gerald Hawkins was born. Hawkins was an established astronomer at Boston University and the Harvard-Smithsonian Observatory who determined that Stonehenge on the Salisbury Plain in Southern England was a sophisticated ancient astronomical computer. Although others had speculated on the importance of Stonehenge, Hawkins performed an intense study which he published in the journal Nature in 1963. He found astronomical alignments among 165 points of Stonehenge purely associated with the sun and moon. He used a computer to show that a pattern of alignments with twelve major lunar and solar events existed. Whether you consider Stonehenge an ancient observatory, astronomical calendar or calculator, the construction of it was an impressive engineering feat and it is shrouded in mystery!

Henri Becquerel for their groundbreaking investigations in radioactivity. Marie was the first woman to win a Nobel Prize. The scientific partnership of Marie and Pierre achieved world renown and Marie would go on to win a second Nobel Prize. More about Marie at a later date she is a science topic all her own!
