Here's a question for you firearms history buffs. As we know, Hiram Stevens Maxim perfected the machine gun a little before the turn of the century. As I was looking through my American Radio Relay League handbook today, I saw a picture of Hiram Percy Maxim, the grandfather of ham radio. Does anyone know if these two great inventors were related? Father and son? I don't have a picture of H. S. Maxim to see if they even looked alike.
