W: Mr. Hudson, where were you born and raised?
M: I was born in Chicago, but I didn’t live there any more. I was raised in Washington, grew up there until I went to college in New York and then Harvard.
W: Looking back. How did you think your parents shaped your character?
M: Well, it’s hard to estimate entirely. I was quite fond of my parents and considered them very good people. My mother was a kind of very feminist and a well-known Jewish poet. She became internationally known. My father was a lawyer. And though it’s hard to say how much they influenced me, I liked them, I respected them and I’m sure I was influenced to some degree by them.
W: You were educated in the public schools?
M; We moved almost every year, so I went to a different public school each year.
W: So you would have been in high school and what years... approximately?
M: Oh, I was in high school when... 26 or 27? I forgot. I graduated from high school in 32.
W; What did you study in university?
M: Well, that’s a difficult question. I started out thinking I’d be an economist, and then I got disappointed with that. And after an odd experience in my junior year, I decided that I’d go out and study agriculture or management, but I enrolled in both for a whole year and tried to learn the required courses. I lasted a year, and then I came back to the main campus and finished up as an economics major specializing in labor economics.
W: Did you go right graduate school or join the army after you graduated from the university?
M: Well, I went to Harvard as a graduate student in philosophy in 1936, and stayed there until the war broke out. I was drafted after I took my PhD exams in the early part of 1941. So I went into the army before Pearl Harbor.
