50s/60s science fiction... Does any one remember these books?

[weaselwomble]

Hi all. My Dad was talking the other day about the books that got him in to reading but unfortunately can't remember the author or title. I would love to find them and buy them for him. There isn't a lot to go on unfortunately but someone might just remember.
So he read them as a child so 50s/60s. It was a series of kids books about a space man and I think the main character was called Kelso. And everything began with a K (place names, character names etc).
I have trawled through wiki, good reads etc and so hoping it rings a bell for someone on here. Tia

Kimball Kinnison - battling to save the world from the evil zwilnik smugglers under the guidance of Arisia?
They are the "Lensman" series by e.e. doc smith (sic) - you can find out about them here

Thank you PomBear. I have sent him the link, it looks promising though!

I remember those! Very juvenile, but I enjoyed them at the time!

I don't think he will read them again but he said he has tried to find them himself a few times just out of curiosity. I thought he might like to have a copy for nostalgic reasons.

Do let me know if they are the right ones

He said no @Pom thank you anyway for trying. Back to the drawing board

Aww poo! I was all smug cos I thought I got it I will have another think and see if I can come up with another suggestion...

It did sound promising! Tbf there isn't Mich to go on but that's all he can remember apparently

Could this be it?
en.m.wikipedia.org/wiki/Kemlo

@hedwig thank you that's the one! He said thank you so much Obviously he had got the character name wrong but how on earth did you find that?

I hate you Hedwig !!!
Not really but poobah! to you for getting that when I didn't!
Go on, thumb your nose and ner ner ne ner ner at me - I can take it
you clever thing you!

Also how on earth do you "tag" without it showing an @ sign?

I just put Hedwig's name in bold - use an immediately before and after the words you want to bold like this*
(if that's what you mean?)

God I'm thick sometimes. Duh! Thank you PomBear

I have to admit Google did the work!
I searched Kelso and 1950s science fiction books, google suggested Kemlo.
Glad your Dad was pleased. They are available on Amazon Kindle
