Alan Graham MacDiarmid
Alan Graham MacDiarmid was born a Kiwi (a New Zealander) in Masterton, New Zealand on April 14, 1927, and still is a Kiwi by New Zealand law, although he becames a naturalized United States citizen many years ago in order to have the right to vote in US elections and, hence, voice his political opinions in a meaningful way.
He was born in Masterton, New Zealand as one of five children - three brothers and two sisters. His family was relatively poor, and the Great Depression made life difficult in Masterton, due to which his family shifted to Lower Hutt, a few miles from Wellington, New Zealand. At around age ten, he developed an interest in chemistry from one of his father's old textbooks, and he taught himself from this book and from library books. He was educated at Hutt Valley High School and Victoria University of Wellington.
In 1943, MacDiarmid passed the University of New Zealand's University Entrance Exam and its Medical Preliminary Exam. He then took up a part-time job as a "lab boy" or janitor in Victoria University of Wellington, during his studies for a BSc degree, which he completed in 1947. He was then appointed demonstrator in the undergraduate laboratories. After completing an MSc in chemistry from the same university, he later worked as an assistant in its chemistry department. It was here that he had his first publication in 1949, in the scientific journal Nature.
He graduated in 1951 with first class honours, and won a Fulbright Fellowship to the University of Wisconsin–Madison. He majored in inorganic chemistry, receiving his M.S. degree in 1952 and his PhD in 1953. He then won a Shell Graduate Scholarship, which enabled him to go to Sidney Sussex College, Cambridge, where he completed a second PhD in 1955.
MacDiarmid worked in the School of Chemistry at the University of St Andrews in Scotland for a year as a member of the junior faculty. He then took a faculty position in chemistry at the University of Pennsylvania, where he became a full Professor in 1964. MacDiarmid spent the greater part of his career on the chemistry faculty of the University of Pennsylvania, where he taught for 45 years. The first twenty years of his research there focused on silicon chemistry.[citation needed] He was named Blanchard Professor of Chemistry in 1988.
His best-known research was the discovery and development of conductive polymers - plastic materials that conduct electricity. He collaborated with the Japanese chemist Hideki Shirakawa and the American physicist Alan Heeger in this research. The three of them shared the 2000 Nobel Prize in Chemistry for this work.
The Nobel Prize was awarded for the discovery that plastics can, after certain modifications, be made electrically conductive. The work progressed to yield important practical applications. Conductive plastics can be used for anti-static substances for photographic film and 'smart' windows that can exclude sunlight. Semi-conductive polymers have been applied in light-emitting diodes, solar cells and displays in mobile telephones.
Future developments in molecular electronics are predicted to dramatically increase the speed and reduce the size of computers.
He died on February 7, 2007. He is buried at Arlington Cemetery Co in Drexel Hill, Pennsylvania.
