Life
He was born in Burton-on-Trent the son of Rev Henry Day who was headmaster of the Grammar School. Originally adopting a life in the brewing industry (typical of Burton-on-Trent, and having moved to Edinburgh to pursue that career, his religious views led him to abandon this in the 1890s and instead pursue a new use for his chemical skills. After some studies in Europe, he began a photo-engraving business. In 1894 he joined Edinburgh photographer John Hislop and in 1897 they formed Hislop and Day. They moved to new premises at 9 Albany Street in the Edinburgh New Town in 1901. The company survived until 1963. In 1917 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were fellow-geologists John Horne, Benjamin Peach, Sir John Smith Flett, and Cargill Gilston Knott. In Edinburgh his address was 36 Hillside Crescent an attractive flat just north of Calton Hill. He was President of the Edinburgh Geological Society 1921–2. He died in Edinburgh on 13 June 1935. He left £500 to the Edinburgh Geological Society in his will.
