Felix Klein may be seen as a “bird/beaver” hybrid, in view of the calculational view on complex multiplication and class fields in the 19th century, leading to modular equations etc. Klein’s “icosahedron” and Weber’s 3 vol. “Algebra” (the best until v.d. Waerden’s book and E. Noether’s school). link A more modern example may be this, but I know only a part of the story.

Right, makes sense.
I just remember a very nice online docu on the Chudnovsky brothers, an old NY’er article , the “one mathematician in two brains”.
