With regard to your entry on Malthus I would make two observations.

He never referred to himself as 'Thomas'.  His friends and family 
called him 'Robert' and he signed himself T. R. Malthus in formal 
writings.  I'd add, therefore, that no serious student of his work 
from Keynes onward refers to him as 'Thomas', though plenty of the 
non-serious ones do.

I'd also query the phrase 'eventually leading to catastrophic 
famine'.   The distinctive feature of Malthus's principle of 
population was that it had always been in operation; it was not a 
prediction of what might happen 'eventually'.  Whether it led to 
famine depended on whether other checks were in operation to curb 
what was 'constant' pressure.  Hence too, of course, Darwin's 
borrowing of the idea, which would not have helped to prove 'natural 
selection' if the pressure was not ceasely in operation  as a result 
of competition for food.
