I read these as a child in the 60's. When Purple House Press re-issued them, I snapped them up. They've also re-issued some other favorites, like the Alvin Fernald series. I like to buy direct from them, so they don't have to share the money with amazon.

Now if someone would re-issue the Miss Pickerel series...

Miss Pickerell!!!! You have no idea how long I’ve been trying to remember her name! I remembered it started with a P, she went to outer space, and liked pistachio ice cream. That turns out to not be enough to google her. Thank you!

Glad to be of help. I think the only one I have (yes, I kept all my SBS books) is Miss Pickerell Goes To Mars.

I think it was peppermint she liked. I read a bunch of the Miss Pickerell as a kid.

Like you I picked up the hardcover reprints.

Now I find there was a 4th Mad Scientist's book published posthumously that came and went (The Big Chunk of Ice). Off to eBay....
