Follow-up 1: Almost one year ago, I posted a list of UK philosophers who were among the combatants in WWI. I've added another name to that list: Leon Roth, who served in the Jewish Battalion of the Royal Fusiliers. Like Rupert Clendon Lodge (see previous post), Roth won Oxford's John Locke Scholarship in Mental Philosophy and taught at Manchester University before leaving England. Roth then taught at the Hebrew University in Jerusalem.
It's been easier to identify French or German philosophers who fought in WWI. I guess that's because France and Germany sent higher percentages of their male populations to one of the fronts, including many more middle-aged men, who were old enough to have begun a career in academic philosophy.
Follow-up 2: In October, I posted a note on Caporetto. Since then, Mark Thompson has written in the TLS about Hemingway's sources for descriptions of the battleground in A Farewell to Arms. Other American writers who volunteered for ambulance duty in WWI include John Dos Passos and E. E. Cummings. John McGrath Morris has written a book about Hemingway and Dos Passos: The Ambulance Drivers.
Follow-up 3: I ended my recent post on Hegel in Canada with a note about Rupert Clendon Lodge. As I noted in 2016, one of Lodge's undergrad students was Marshall McLuhan. Lodge also taught the novelist W. O. Mitchell, who based a character (Dr. Lyons) partly on Lodge in Since Daisy Creek. So, add this to my "philosophers in fiction" set of posts.
Also, while there's no Wikipedia entry for Rupert Clendon Lodge, his relatives are certainly well represented there. One of his uncles was a physicist, Sir Oliver Lodge. Another uncle was a historian, Sir Richard Lodge. Rupert's aunt was also a historian, Eleanor Constance Lodge (CBE). A third uncle was the mathematician Alfred Lodge. Rupert's grand-uncle was Rev. Samuel Lodge. Among Rupert's 1st-cousins were Alexander Lodge and Oliver W. F. Lodge. Still more of his relatives have Wiki entries.
