The Ngram below is a graph of the frequency of mentions of military leaders of World War II.
George Patton (United States), Erwin Rommel (Germany), Isoroku Yamamoto (Japan), and Bernard Law Montgomery (United Kingdom) all saw a spike in the early 1940s, at the height of the war.
Erwin Rommel and George Patton saw the biggest spike and then a steady climb into the new millenium.
Isoroku Yamamoto and Bernard Law Montgomery dipped back down after their spike and then remained consistent.
Georgy Zhukov (Soviet Union) did not enjoy the same bump his colleagues did, and remained realatively unmentioned.
