**Harold Seymour Shapiro** (born 1928 in Brooklyn, New York) is a professor emeritus of mathematics at the Royal Institute of Technology in Stockholm, Sweden, best known for inventing the so-called Shapiro polynomials (also known as Golay–Shapiro polynomials or Rudin–Shapiro polynomials) and for work on quadrature domains.^{[citation needed]}

His main research areas have been approximation theory, complex analysis, functional analysis, and partial differential equations. He is also interested in the pedagogy of problem-solving.

Shapiro earned a B.Sc. from the City College of New York in 1949 and earned his M.S. degree from the Massachusetts Institute of Technology in 1951. He received his Ph.D. in 1952 from MIT; his thesis was written under the supervision of Norman Levinson.^{[1]} He is the father of cosmologist Max Tegmark, a graduate of the Royal Institute of Technology and now a professor at MIT.^{[citation needed]}
