||1952: Forest Ray Moulton dies ... astronomer and academic. In the first decades of the twentieth century, some additional small satellites were discovered to be in orbit around Jupiter. Dr. Moulton proposed that these were actually gravitationally-captured planetesimals. This theory has become well-accepted among astronomers. Pic.


||1960: Walter Noddack dies ... chemist who discovered the element rhenium (Jun 1925) in collaboration with his wife Ida Tacke. In 1922, he began a long search for undiscovered elements. After three years, the careful fractionation of certain ores yielded element 75, a rare heavy metallic element that resembles manganese. Named rhenium after the Rhine River, it was the last stable element to be discovered. Noddack is also remembered for arguing for a concept he called allgegenwartskonzentration or, literally, omnipresent concentration. This idea, reminiscent of Greek philosopher Anaxagoras, assumed that every mineral actually contained every element. The reason they could not all be detected was they existed in too small quantities. Pic: https://sciencenotes.org/today-in-science-history-december-7-walter-noddack/
