You're not pedantic, you're right. That is even more painful...
One should never believe whats friends say. I was told the original design was Mitchell's. It wasn't.
From a Mosquito site:
"The members of the Mosquito design team included the chief designer and team leader, R. E. Bishop, Richard M. Clarkson, assistant chief engineer and Mosquito aerodynamicist, C. T. Wilkins, assistant chief designer and the fuselage specialist, W. A. Tamblin, senior designer and the wing specialist, and Fred Plumb who managed constructing the prototype."
