William Gilbert "Gil" Strang (born November 27, 1934^[1]) is an American mathematician known for his contributions to finite element theory, the calculus of variations, wavelet analysis and linear algebra. He has made many contributions to mathematics education, including publishing mathematics textbooks. Strang was the MathWorks Professor of Mathematics at the Massachusetts Institute of Technology.^[2] He taught Linear Algebra, Computational Science and Engineering, and Learning from Data. His lectures are freely available on MIT OpenCourseWare.

Strang popularized the designation of the Fundamental Theorem of Linear Algebra as such.^[3][4]

Gilbert Strang was born in Chicago in 1934. His parents William and Mary Catherine Strang migrated to the USA from Scotland. He and his sister Vivian grew up in Washington DC and Cincinnati, and went to high school at Principia in St. Louis.

Strang graduated from MIT in 1955 with a Bachelor of Science in mathematics. He then received a Rhodes Scholarship to the University of Oxford, where he received his B.A. and M.A.^[5] from Balliol College in 1957.

Strang earned his Ph.D. from UCLA in 1959 as a National Science Foundation Fellow, under the supervision of Peter K. Henrici. His dissertation was titled "Difference Methods for Mixed Boundary Value Problems".^[6]

While at Oxford, Strang met his future wife Jillian Shannon, and they married in 1958. Following his Ph.D. at UCLA, they have lived in Wellesley, Massachusetts for almost all of his 62 years on the MIT faculty. The Strangs have three sons David, John, and Robert. They describe themselves as a very close-knit family. He retired on May 15, 2023 after giving his final linear algebra lecture at MIT.^[7]

Strang's teaching has focused on linear algebra which has helped the subject become essential for students of many majors. His video lectures are popular on YouTube and MIT OpenCourseWare. Strang founded Wellesley-Cambridge Press to publish Introduction to Linear Algebra (now in 6th edition) and ten other books.

Professor Strang's video lectures at MIT are open to everyone. They are watched worldwide (more than 20 million viewers). They include 3 popular courses and the final lecture in 2023^[8].
