teaching fellowship as well. Under Lewis's supervision, Spedding earned his Doctor of Philosophy (Ph.D.) in 1929, writing his thesis on "Line absorption spectra in solids at low temperatures in the visible and ultraviolet regions of the spectrum". It was published that year in the Physical Review. Early career Spedding's graduation coincided with the onset of the Great Depression, and jobs became hard to find. Spedding received a National Research Fellowship from 1930 to 1932, enabling him to stay at Berkeley and continue his research into the spectra of solids. While hiking in northern California, he met Ethel Annie MacFarlane, who shared his passion for camping, hiking and mountain climbing. Born in Winnipeg, Manitoba, she was a graduate of the University of Saskatchewan and the University of Toronto, where she had earned a master's degree in history. When they met, she was teaching at Victoria High School in Victoria, British Columbia. They were married on 21 June 1931. They had a daughter, Mary Anne Elizabeth, who was born in 1939. From 1932 to 1934, Spedding worked for Lewis as a chemistry instructor. Around this time, he became interested in the chemistry of the rare earths. These were expensive and hard to find, and generally available only in minute amounts. In 1933 he won the Irving Langmuir Award for most outstanding young chemist. The award came with a cash prize of $1,000. He borrowed money to travel to Chicago to collect it. While he was there, he was approached by a man offering several pounds of europium and samarium. His benefactor was Herbert Newby McCoy, a retired chemistry professor from the University of Chicago, who had obtained a supply of these elements from the Lindsay Light and Chemical Company, where they were a byproduct of thorium production. A few weeks later, Spedding received a package in the mail containing jars of the metals. In 1934, Spedding was awarded a Guggenheim Fellowship, allowing him to study in Europe. To save money, Spedding and his wife travelled to Europe by heading westward across the Pacific. His intention was to study in Germany under James Franck and Francis Simon, but they fled Germany after Adolf Hitler came to power in March 1933. Instead he went to the Cavendish Laboratory at the University of Cambridge in England, where he was welcomed by Ralph H. Fowler. Spedding worked with John Lennard-Jones, and attended lectures given by Max
