Paul Nahin's biography of Oliver Heaviside is a find, too. Nahin and Sobel between them have sewn up the historical science biography field. Heaviside's own books are available to buy, and are filled with neglected gems.

While I'm here, Don Eyles's account of the Apollo program and his role programming the moon landing, "Sunburst and Luminary" is notable. Ordered directly from his website https://www.sunburstandluminary.com/SLhome.html , it was delivered with gratifying alacrity.

Further afield, I read "Reading the Rocks: The Autobiography of the Earth", by Marcia Bjornerud aloud to my kids. Their attention did not wander. Mine either. https://bookshop.org/books/reading-the-rocks-the-autobiograp...

Heaviside is buried near where I live. Minus the talent I empathize with his journey somewhat so I should really go and pay him a visit.
