# A list of my teaching fellows, with some notes about courses I have taught **A note on the genealogy of the Harvard CS courses I have taught** Some time in the 1950s or early 1960s (I will tighten up this history when I have time), the basic digital computing course acquired the designation Engineering Sciences 110 or Eng Sci 110. Programming was in assembly language. In the fall of 1968, Bill Bossert started teaching a Gen Ed course he dubbed Nat Sci 110 to expose the general audience of Harvard students to the possibilities of computing. These courses were hugely influential, but I never took either of them or any other intro programming course; I had learned a little programming in an MIT summer course while I was in high school, learned more in a job in the Psych Dept, and then jumped into AM252r, Ivan Sutherland's computer graphics course. I took over Nat Sci 110 (from Chuck Prenner, who had taken it from Bossert) in the fall of 1975, my second year on the faculty. At some point in the 1960s Eng Sci 110 became Applied Math 110, probably because Tom Cheatham had taken it over and it became more recognizably a Computer Science course, except that there was no such thing in the Harvard gazeteer. It was assembly language and Lisp programming, with a slant toward data structures and basics of programming language processing. The final project was to impelment a Lisp interpreter in assembly language. I took over that course in the spring of 1979. Meanwhile in the fall of 1978 I created AM 108, Introduction to Fomal Systems. This was the first undergraduate course at Harvard on "CS theory" -- automata, formal languages, and computability -- before that time CS theory was a purely graduate subject, taught in AM207, a course I had taken from Sheila Greibach while I was an undergraduate. (I neither understood nor appreciated the subject at the time!) There was already an AM106 (Applied Algebra) and AM107 (Combinatorics, a course I also taught briefly, and which was later renumbered as AM122, its present number). So 108 was really the next available number. (This course would eventually become CS121, *v.i.*) So that year 1978-79 I was teaching two courses I had not taught previously, one of them a course that was new to Harvard. In the academic year 1981-82 I created two more courses from scratch. In the fall I taught Applied Sciences 11, an intro to CS that was meant for majors but was not as grueling and super-techy as AM 110, and was more disciplinary than Nat Sci 110. (Nat Sci was renumbered AS 10, the Gen Ed program having given way to the Core, and Nat Sci therefore no longer being an extant rubric. It did not long survive, having no foothold in the Core Curriculum.) We used Pascal in AS 11. This is the course that would become CS 50 (*v.i.*). (I was actually teaching AM 108 at the same time as I taught AS 11 for the first time. Whew!) Then in the spring I taught AM 119 for the first time, a new course, an undergraduate data structures and algorithms course. Prior to that data structures was a graduate subject (AM 219; there was briefly a "control structures" course at the graduate level too). AM 119 would become CS 124. In the fall of 1983 we got approval to offer a CS concentration and to start calling our courses "Computer Science". AS 11 then became CS 11, AM 108 became CS 121, AM 110 became CS 150, and AM 119 became CS 124. I picked up CS 150 again, migrating it to C, and then in 1989 we did another renumbering, rebranding CS 11 as CS 50 and CS 150 as CS 51 to solidify the notion that these two courses were conceived as sequential. So the genealogies are Eng Sci 110 -> AM 110 -> CS 150 -> CS 51, AS 11 -> CS 11 -> CS 50, AM 107 -> AM 122, AM 108 -> CS 121, and AM 119 -> CS 124. (There was a logic to some of this; the penultimate digit of a CS course designated the area, with 2 being theory, 5 being languages and programming systems, 4 being hardware and networks, and so on. So when I created an intro discrete math course for computer scientists in 2012, it was natural to dub it CS 20. Likewise "9" was for reading and research courses, so it made sense to label my "Classics of CS" course as CS 191.) I also created a Core course called Quantiative Resoning 48, "Bits," from which my *Blown to Bits* book (now in its [second editon](https://www.amazon.com/Blown-Bits-Liberty-Happiness-Explosion-dp-0134850017/dp/0134850017/ref=dp_ob_title_bk)) emerged. It struggled to make the transition to Gen Ed II, under the rubric Empirical and Mathematical Resoning 12, and died soon thereafter. For a narrative version of the history of some of the early courses mentioned above, see my Harvard Magazine article, [A Science is Born](https://www.seas.harvard.edu/news/2020/08/science-born). **An Almost Complete List of all the Courses I have taught and all my Teaching Fellows (\* = Head TF)** 1974 - 75 *AM 208* Seth Breidbart *Math 286* 1975 - 76 *Nat Sci 110* Nancy Boxer Glenn Bresnahan John Burruss Norman Cohen Bob Faulkner\* Steve German Jeff Herrmann Beau James David Leinweber Henry Leitner Larry Morse Greg Nelson Eric Roberts Annie Shum Alfred Spector Joel Weisberg Greg Whitten *AM 122* Seth Breidbart? *AM 262* Mike Genesereth 1976 - 77 *Nat Sci 110* John Burruss Bob Case Norman Cohen Steve Dyer Kent Fielden Zachary Goldberg Bruce Gordon Bob Greenberg Eric Hamilton Jeff Herrmann Beau James Lew Lasher David Leinweber Henry Leitner Bill Lofton Christos Papadimitriou Eric Roberts\* Barbara Trombka \[Blaustein\] Debbie Washington \[Brown\] (Spring term - leave) 1977 - 78 *Nat Sci 110* Joshua Barnes Robert Case Norman Cohen Monte Davidoff Tom Dinger Kent Fielden?
