Professor Alexander William Bickerton (7 January 1842 – 21 January 1929) was the first professor of chemistry at Canterbury College (now called the University of Canterbury) in Christchurch, New Zealand. He is best known for teaching and mentoring Ernest Rutherford. He was a natural teacher though an eccentric one, who taught science in an exciting way. His differences were not limited to teaching as he formed a socialist community in Christchurch, which he later set up as a theme park. His partial impact theory explaining the appearance of temporary stars was the major work of his lifetime. Early life Alexander William Bickerton, was born on 7 January 1842, at Alton in Hampshire, England, the second son of Richard Bickerton, a builder's clerk, and Sophia Eames. His parents had both died before he left school. After not excelling at grammar school his uncle found him work in a railway workshop and later he worked in an engineering office. With inheritance money he set up a wood-working factory using machines that he had invented, but by 1864 the factory was in debt. Teaching in England Around this time Bickerton started attending science classes held in the area. His teacher Moses Pullen realised Bickerton had a natural talent for the subject and suggested he take up teaching science. By 1866 Bickerton was teaching science in Birmingham, while he was there he sat examinations for the Royal Exhibition for the School of Mines where he gained honours. In 1867 he moved to London where he was taught by prominent scientists of the time Edward Frankland, John Tyndall and Thomas Huxley. These influences increased Bickerton's passion to teach, but London was not as receptive to science teaching as Birmingham had been, and Bickerton's first class attracted just one person. To attract more students he looked at how successful preachers drew in large numbers. From his observations he said: "to instruct the Londoner you must make your class as entertaining as a music-hall and as sensational as a circus." This would characterise his teaching throughout his career. Before long his classes became very popular, and by 1869 he was teaching hundreds of students. In 1870 he took up a job offer to organise science work at the Hartley Institute, a position he held for three years until he became unhappy with conditions and sought other work. Life in New Zealand It was in 1873 that Canterbury
