I love used books stores. No surprise there. But wandering through the Friends of the Free Library bookstore at 20th and the Parkway, I saw this Modern Physics book from the 1920's. Which of course, I also loved and was ready to snatch up for $3 when I noticed the author was...
CHARLES E. DULL!
A descendant or cousin of the Charles B. Dull for whom I wrote a poem this summer? Perhaps I will call Laurel Hill cemetery and ask them.
Apparently, physics in the 1920's was not so far off. If you check Amazon, this book is still in circulation.
