He is credited with developing the theory of continuous selections. The Michael selection theorem is named for him, which he proved in. Michael is also known in topology for the , a paracompact space whose product with the topological space of the irrational numbers is not normal. He wrote over 100 papers, mostly in the area of general topology. Michael died in 2013 at the age of 87.
