Ejection of Computer Science from Mathematics

In the US, CS departments are about 50/50 spinoffs of math departments and spinoffs of EE departments; how do the latter fit into this?

Quoting my 2019 message to the cctech mailing list:

> The genealogy of Computer Science departments (and their curricula) (at least in the US) is also weird and historically-contingent. Basically it seems to have been a tossup at any given school whether it came out of the Electr[ical|onic] Engineering department, in which case it was memories and logic gates and a bottom-up, hardware-focused curriculum, or out of the Mathematics department, in which case it was algorithms and complexity analysis and a software-focused curriculum.

Yes, I've noticed the same thing. Example: Harvard's CS department is originally from the math side, while MIT's is from EE (thus today's EECS).

Berkeley = EE

Brown = Math

BYU = Math

Caltech = EE

Columbia = EE

Cornell = Operations research, math

Dartmouth = Math

Illinois = Math

NYU = Both (because Polytechnic developed its own CS program long before NYU acquired it to regain an engineering school)

Penn = EE

UCLA = OR (probably because of the RAND heritage)

Caltech until very recently did not formally offer CS degrees; students received degrees in Engineering and Applied Science, with a focus on CS (or aeronautics, or civil, or ME).

Illinois is an example of a track we might call "other" or even "defense". With government funding the university built its own computers (including ILLIAC and PLATO), and the group that did so became the CS department, but the undergraduate CS program began within the math department. Harvard's and Penn's programs might also qualify.

Undergraduate CS degrees are BA (Example: Harvard), BS (Example: Penn), or both (Example: Columbia). At Penn one must be an engineering student to major in CS. At Columbia one can major in CS in either the liberal arts or engineering schools, but with different curriculums. At Yale there is one undergraduate school, within which one can receive a BA or BS in CS, with different curriculums. Cornell, Northwestern, and Berkeley offer CS in their separate liberal arts and engineering schools; undergraduates receive BA or BS degrees with identical CS curriculums, with only other requirements differing.

I've read that medical schools are good at teaching either pharmacology (drugs), or pathology (diseases); perhaps this is also because of the expertise/specialty of their early faculty members.
