I didn't even consider those because I thought OP meant adult mysteries.
You forgot Hardy Boys and Nancy Drew (yes I admit I have read a few).
You will be surprised that most of these authors are unknown to the present generation in the US. I think Enid Blyton was never known here. Hardy Boys and Nancy Drew yes, even movies made on them, but they are probably as unfamiliar as Laurel and Hardy.
It has something to do with the colonial tradition I think.
Tintin and Asterix are also virtually unknown here, until Spielberg's movie on Tintin.
