William Joseph Wiswesser (December 3, 1914 – December 17, 1989) was an American chemist best known as the creator of the Wiswesser line notation (WLN), which was an innovative way to represent chemical structures in a linear string of characters suitable for computer manipulation. He is also known for the Wiswesser rule, a mathematical formula that predicts the order of atomic orbitals in many-electron atoms.
