ADMIRAL WILLIAM HENRY PURNELL BLANDY:  
The officer in charge of Joint Task Force 1.  

His nick-name was Spike, and he also has the dubious
distinction/nickname "Atomic Playboy".  Here's a
quote of his from July 25, 1946:

T
he bomb will not start a chain-reaction in the water
converting it all to gas and letting the ships on all the
oceans drop down to the bottom. It will not blow out
the bottom of the sea and let all the water run down
the hole. It will not destroy gravity. I am not an atomic
playboy, as one of my critics labeled me, exploding
these bombs to satisfy my personal whim
