A question that has been asked by visitors here on several occasions over the last few years is "How tall was C. S. Lewis?". We've never been able to provide a good answer. Colin Duriez has published a new biography/timeline, with the information. According to Lewis' 1917 induction physical into the Royal Army Officer Training Corps, Lewis was 5' 10 3/4" and weighed 13 stone (about 180 pounds).
Duriez's new book is titled The C.S. Lewis Chronicles. It's a fairly interesting read, goes through Lewis' life year-by-year, listing important events in his life as well as in the world at large.
