What was discovered
Algebraic topology theorem, due to Herbert Seifert and Egbert van Kampen, which computes the fundamental group of a space from the fundamental groups of two open, path-connected subspaces covering it.

- Standard tool for computing fundamental groups of complex spaces
- Applications in the classification of surfaces and knots
- Later extensions via fundamental groupoids
