It is strange we don't hear much about him, considering he invented the flipper and claimed to have invented the pop bumper, too. It seems like people only talked to Harry Williams and Steve Kordek back then.

Here are a couple of pictures of him I found online:ae87fc5efd3f1b847e398fc30362f5b4_(resized).jpg562b5ce4cc57ae5a2097d1785dce2259_(resized).jpg

In that bottom one he looks a little like Shemp Howard.

Oh, those are some beautiful games, by the way. Love to see a short flipper game in good shape.

I would guess that they knew each other. I believe they worked at Gottlieb at the same time. I found one little snippet from a video game history site that said Harry was well liked, but known to be strict and serious about his job. That's about all I can find so far, other than the note from IPDB about him writing in to a vendor magazine to claim he invented the pop bumper in the 30s. I guess him dying in 1960, before people got all nostalgic about the business, kept us from hearing more from him directly.
