When was Ernest Griffin, one of the human geographers known for the Griffin-Ford model, born?

Doing a report on Ernest Griffin, the geographer, for AP human geography, and can't find his birth date anywhere.

You can ask him by sending him an email here:
egriffin@mail.sdsu.edu
By the way, his first name is Ernst, not Ernest
Based on the year he graduated college (1965), he was probably born in 1943.
The Griffin-Ford Model of the layout of Latin American cities was presented in 1980.

He graduated in 1965.
A.B. San Diego State University, 1965

The AB takes 3 to 4 years to complete, so if he began when he was 18 he would have graduated at 21 or 22 y.o.

So he would have been born in 1943 or 1944. And would presently be about 71 or 72 y/o
