August 10, 2018, marks the 100th birthday of one of the great men in nuclear power: Vice Admiral Eugene P. “Dennis” Wilkinson USN. He passed away in July 2013, a month before his 95th birthday.
I was privileged to call Dennis Wilkinson friend for more than 33 years. He left an enduring impact on everyone who knew him. I was honored that he trusted me to write his authorized biography, UNDERWAY ON NUCLEAR POWER, The Man Behind the Words, Eugene P. “Dennis” Wilkinson, Vice Admiral USN. The book was published in 2016 by the American Nuclear Society (available from ANS and Amazon). The world is a better place because of Dennis Wilkinson, and I am a better person for having known him.
