Albert Potter Wills (1873–1937) was an American physicist who researched magnetic materials and was the PhD advisor of the Nobel Prize winner Isidor Isaac Rabi. During his career he investigated magnetic susceptibilities, magnetic shielding, magnetostriction, conduction of electricity through mercury vapor, and hydrodynamics. He also wrote a textbook on vector analysis. Wills received his PhD from Clark University in 1897 under Arthur Gordon Webster with a thesis entitled: On the susceptibility of diamagnetic and weakly magnetic substances.
