Are there classes dedicated to understanding the work of a particular mathematician?
I have seen courses dedicated to a theorem (I saw for example one that sought to prove and understand the Atiyah-Singer Index theorem, or the prime number theorem.) But I'm wondering about a mathematician-- which sounds difficult given that the prerequisites may be sporadic, but I'm curious if sometimes a course may not culminate in just one theorem, but just cover the work of a prominent mathematician.
I suppose conversely, some courses are dedicated to a particular point of view, such as Algebraic Geometry courses that seek to follow the "Grothendieck philosophy," but this seems difficult from following EGA or something like that.
To clarify, I'm not asking about the pedagogical merits of such a course (although that is an interesting question in and of itself.)
If the course curriculum is available, I would also love access to it.
