Another very good book about Oliver Heavyside is 
Paul Nahin's  Oliver Heaviside: Sage in Solitude: The Life, Work,

and Times of an Electrical Genius in the Victorian Age:

Yes.  However, Oliver Heaviside had the advantage of both vector 
calculus and operational mathematics which he sort of invented.  Maxwell 
did it "old school." Regardless of who you favor, the theory took on new 
meaning for me when a professor pointed out ...


"We can measure electromagnetic radiation from it's earliest beginnings 
and many billions of light years away in any direction we choose and it 
always obeys Maxwell's analysis to whatever precision we can muster."  
And, my life-long hobby works because of that.

There is an excellent book on Heaviside, who was a genius in his own right:

“The Forgotten Genius of Oliver Heaviside”, available on Amazon, see 
https://www.amazon.com/Forgotten-Genius-Oliver-Heaviside-Electrical-ebook/dp/B01N0S90BN/ref=sr_1_1?keywords=genius+heaviside=1585197188=8-1
 


Just in case anyone is looking for a good book in this time of self-isolation,.

I have often recommended Daniel Fleisch’s book, A Student’s Guide to Maxwell’s 
Equations, to my students.  In it he credits G. F. FitzGerald, Oliver 
Heaviside, Oliver Lodge, and Heinrich Hertz for simplifying Maxwell’s equations 
to the few that we often see today.

I heartily recommend this book, the best I have seen on Heaviside 
https://www.amazon.com/Maxwellians-Cornell-History-Science/dp/0801482348 

He had a tough childhood and became a telegrapher and virtually self-taught 
physicist who laid the foundations for modern electrical engineering.
