“A most engaging boy, brimful of fun and mischief, a high intellectual forehead, with fair, curly hair and a beauty that was almost girlish.”
William Thomson remembered here by a fellow Cambridge undergraduate. (Pencil portrait of William Thomson at 16 by Elizabeth Thomson. Courtesy of the National Portrait Gallery, London.)
“One of the most valuable of these truly scientific, or science-forming ideas….”
For James Clerk Maxwell (pictured here), Thomson’s ingenious mathematical analogy between the geometry of electric forces and the flow of heat was the first step in turning Faraday’s acute insights into the modern theory of electromagnetism. (Photograph from Lewis and Garnett, 1884.)
“Telegraphic work … possesses a combination of physical and … metaphysical interest, which I have never found in any other scientific pursuit.”

“A friendly and unconstrained party….”

“Lord Kelvin is a gentleman of exceedingly pleasant manners [and] amiability of disposition … a remarkable example of a great man whose native character has remained unchanged despite … the elevation to a lofty social position.”

“What I liked best was when he left us to follow or not as we could, and went on thinking aloud, as he sometimes did. His mind was full of fancies, brimming over with metaphors….”
A student recollects Kelvin as a teacher, photographed here at his last lecture, in 1899. (Photograph from Thompson, 1910.)
“Our discussions did not always end in agreement, and I remember his admitting that a certain amount of opposition was good for him.”
