Acknowledgements in theses 2

In The Zionist pioneer youth movement in America as a social movement by Joseph Greenblum: "To Erika, for everything words do not express."

Meet the dispassionate Drs. Moody, twins born in 1918 who went through school together, right up through PhDs in physical chemistry.
LeRoy to Leonard, in The molecular kinetic behavior of certain seed globulins:

Mr. L.E. Moody, a fellow graduate student, worked jointly with the author on the preparation of the seed globulins, and has given assistance and advice during the course of this project.

Leonard to LeRoy, in A contribution to the physical chemistry of the seed globulins in solution:

Mr. LeRoy Moody assited in the preparation of the proteins. Without his assistance much of this work never would have been completed.

In Sequential tests for the detection of linkage by Newton Ennis Morton: "My wife, Nancy T. Morton, helped to compile the tables and showed remarkable forbearance at other times."

It seems to my admittedly unscientific eyes that the PhD theses mention spouses' forbearance, assistance, patience, etc. much more frequently than the Masters theses do.
