First Appearance: Captain America (vol. 1) #135 (Mar. 1971): "More Monster Than Man"
Number of Appearances: 1
Note: attacked by dogs controlled by Dr. Gorbo/Monster Ape
SHIELD scientis Dr. Erik Gorbo created a serum that transformed himself into a monster ape, and also gave him the power to mentally control animals.
When Dr. Gorbo (as the "Monster Ape") first tested his power, he tried it out on dogs in New York City. Harry was one of the police officers who were already trying to stop the monster ape from robbing a bank when they were attacked by the dogs. The police were somewhat helpless in this situation because they really did not want to hurt the dogs.
Harry's name is identified in panel 3 on page 15 in Captain America #135. Another police officer shouts at him: "Harry! Look out behind you! Every mutt in town is on the run!"
In the next panel, another police officer (presumably Harry) says: "I--don't get it! It's like--they're helpin' him!"
The police officers trying to stop the bank robbery and then getting attacked by dogs can be seen on page 1 in panels 2, 4 and 5.
