3 - Samuel Bruce McLaren

Date Range1876 - 1916

When S. B. McLaren was killed in World War One, the prevailing sentiment was not only of great sadness but what could have been. His educational achievements and impressive but all too brief career were constantly punctuated by remarks about his "great originality" and future eminence. Posthumously compared to Einstien, Jeans, Planck, Laue and Abraham, McLaren’s research on the theory of radiation was considered both unique and exciting.

Born on 16 August 1876 at Yedo in Japan, Samuel Bruce McLaren moved to Melbourne with his parents at the age of five. Instilled with a passion for learning and truth, Bruce McLaren was educated at Coburg State School, Brighton Grammar and Scotch College and at the University of Melbourne. He graduated in 1897 with first class honours in mathematics and was awarded the Wyselaskie Scholarship in mathematics and the Dixon Scolarship in natural philosophy.

In the following year, McLaren made the pilgrimage to Trinity College, Cambridge where he "worked like a slave" and graduated B.A. with first class honours in 1900 and received the Isaac Newton Research Scholarship in 1901. At the time a teacher observed, "I regard him by far the ablest student I have lectured to during twelve years I have been here. His mathematical and physical insights were most uncommon, I have always expected great things from him." Yet McLaren’s interests went far beyond the confines of mathematics alone, he was also enthralled by the social sciences, music, travel, philosophy, sport, art and literature.

After a brief respite in Australia, McLaren returned to England in 1904. He was appointed lecturer in mathematics at University College, Bristol and subsequently transferred to Birmingham University two years later. The constant letters home are testament to McLarens’s homesickness but the decision to live in England allowed him access to an privileged environment to observe the immense developments in mathematical physics which challenged his own fundamental ideas and to befriend a fascinating milieu of intellectuals on the fringes of the Bloomsbury set. Although McLaren enjoyed these advantages he remained ambivalent about England and highly critical of its repressive class system.

1913 would prove a watershed in McLaren’s life when he applied for the position of Professor of Mathematics at Reading University College. Although he was a late candidate, McLaren was successful and he impressed the selection committee as a man "who breathed freshness and fullness of life and vigour." The confidence in his intellectual capabilities were indeed confirmed as McLaren’s contribution to the theory of radiation was honoured by Cambridge University when he shared the Adam’s Prize in the same year. It was the joint winner, J.W. Nicholson who claimed that McLaren "anticipated Einstein and Abraham in their suggestion of a variable velocity of light, with the consequent expressions for the energy and momentum of the gravitational field." Popular, modest, boyish and approachable, McLaren’s teaching was as impressive as his scholarly achievements.

In June 1914, McLaren returned to Australia for the meeting of the British Association of the Advancement of Science. It would prove a bittersweet homecoming as the outbreak of the first World War was announced and McLaren anguished over his decision to join up. Although courageous and possessing an infinite belief in duty, Bruce McLaren was deeply opposed to violence and was never attracted to military life. Nevertheless he resolved to join up and began to study signalling aboard ship. During the trip back to England, McLaren received the distressing news of his father’s death.

Serving as a Lieutenant with the Royal Engineers, McLaren fearlessness inspired feelings of idolatry amongst his men. Sadly the great potential and expectations for McLaren’s life did not eventuate. In August 1916 at Briquetterie, he was badly wounded in the head when he and two volunteers went out to clear a store of bombs out of a burning ammunition dump. McLaren returned alone to complete the task and was wounded again and died two weeks later. With the exception of his scientific papers that were compiled and printed posthumously, the war precluded McLaren from publishing his work on the fundamental problems of mathematical physics that had enthralled him since Cambridge. J. Nicholson later contended that the premature deaths of both McLaren and Moseley were perhaps the two most irreparable losses to the future of science caused by the war.
