J. Arthur Seebach Jr.

Seebach studied Greek language as an undergraduate, making it a second major with mathematics.

He, his wife Linda A. Seebach, and Lynn A. Steen wrote an expository article "What is a Sheaf".

[1] The paper showed that a sheaf is useful in analysis, algebra, and geometry when considering germs of holomorphic functions, local rings, and differential forms.

The massive effort was eventually distributed over some 50 mathematicians at Saint Olaf, Carleton, and Macalester Colleges.

Seebach and Steen conducted research in a 1967 summer school with students investigating the independence of conditions on topological spaces.
