Name of tetrobots' owners?

[goat]

I've been trying to figure out the full name of each of the tetrobots' owners. Here is the list presented in the logbook:

Tetrobot - Isaac A., Russia
Watabot - Jules V., France
Puddinbot - Arthur D., England
Lumibot - Betty J., Australia
Powerbot - Nikola T., Croatia
Turbot - Balthazar P., Scotland
Steambot - Jack L., Canada
Spacebot - Ellen M., USA

Besides the initials and locations, the excerpts in the logbook themselves contain helpful clues. So far I've managed to figure out Isaac Asimov, Jules Verne, Arthur Conan Doyle, and Nikola Tesla (although I could be wrong) and Spacebot's owner MIGHT be Ellen McLain, the voice actor for GLaDOS.

I'm unable to figure out the rest, so here I am asking for your assistance to help me solve this question.

Heh, I had never noticed the owners are cleverly linked to their bots!

I've been googling for a while but I only was able to figure out those ones too... :/ Ellen is definitely the Portal's voice actress since most of Spacebot's puzzles are based on portals. No idea about Lumibot, Turbot and Steambot though... :/

Steambot is Jack London (1876-1916) author of most famously Call of the Wild and White Fang.

Jack London doesn't have anything to do with neither Canada nor any Steambot's puzzle element... or does it?

I think Turbot's owner Balthazar P. (Scotland) may actually refer to Balthazar Picsou, which is the french name for Walt Disney's Scrooge McDuck, who was born in Scotland.

[Edit] > ...Which is pretty much confirmed by the highly greedy description.

Jack London also wrote the short story To Build a Fire, which the text of the Steambot letter references.

After some googling Betty J. might be Betty Jean Eadie, who wrote a book titled "Embraced by light", which perfectly fits the lumibot. But she's american, not australian, and the ingame text seems to be about the impossible mission series/movies...
