James Gentle's Mathematical Ancestors

My thesis advisor for my PhD in Statistics in 1974 from Texas A&M University was H. O. Hartley.

The line of descent is shown below (each was a student of the prior one).
(You will notice from the pictures that the sequence is monotonically increasing in handsomeness.)
