Alexander Hamilton Phillips (1867-1937) spent his career at Princeton University, first as a student and then as a professor of geology and mineralogy. In 1904 he succeeded in extracting radium from a sample of carnotite from Utah. This was the first radium produced in the United States. He donated this sample of radium to the Smithsonian in 1913.
