The Adams Prize in 1901 was awarded to Hector Munro Macdonald for his research into the diffraction of electric waves. Born in Edinburgh in 1865, he built a career that bridged pure mathematics and physical applications, ultimately serving as a professor at the University of Aberdeen for three decades until his death in 1935.
Early Education and Academic Training
Macdonald began his schooling in Edinburgh before relocating with his family to Easter Ross. He attended the local school near Hill of Fearn and the Tain Royal Academy, later finishing his secondary education at Aberdeen Grammar School. He enrolled at the University of Aberdeen in 1882, graduating with First Class Honours in 1886. He subsequently moved to Clare College, Cambridge, where he was a foundation scholar. In 1889, he finished as the fourth Wrangler in the Mathematical Tripos and secured the second Smith's Prize in 1891.

His primary research focused on the diffraction of electric waves, a field he advanced by summing series of Bessel functions. His 1902 book, Electric Waves, explored the propagation of signals, addressing the scientific challenge of how wireless transmissions appeared to bend around the Earth's surface. While he initially proposed atmospheric refraction as the cause, his mathematical work laid a foundation for understanding these phenomena. In 1904, he addressed a correction concerning the conduct of spheres in a dielectric after receiving feedback from Henri Poincaré.
Professional Service and Recognition
Macdonald maintained a position at the University of Cambridge until 1904, when he was appointed Professor of Mathematics at the University of Aberdeen. He remained in this role for the remainder of his life. During World War I, he engaged in war service in London, working with the Ministry of Munitions and the Ministry of Labour between 1916 and 1919. His contributions were recognized with the appointment as an Officer of the Order of the British Empire in 1918. He also served as the chairperson of the London Mathematical Society from 1916 to 1918.
Final Years
Throughout his career, Macdonald received significant professional honors, including his election as a Fellow of the Royal Society in 1901 and a Fellow of the Royal Society of Edinburgh in 1905. He also held a fellowship at Clare College until 1908 and received an honorary fellowship there in 1914. Macdonald, who never married and had no children, spent his final years living at 33 College Bounds in Aberdeen. He died in 1935 and was buried at St Machar's Cathedral.
