Gordon Lynn Walls. Journal of the History of Medicine and Allied Sciences
1956. XI (1) pp 66-96.
The author of this blog unashamedly echoes these words. Even after extensive efforts digging into the life of Gordon Walls, it is still not clear what his roots were. I own up myself to being bumblesome and I second Gordon Walls' warning that it isn't wise to attempt historical research without training. In other words what Gordon Walls had to say about the mysterious G. Palmer, could also be said about Gordon Walls himself.
From a talk given to the Colour Group of the Physical Society on February 20, by R. A. Weale, and published in Nature, March, 1957.
