John Crank: The Pioneering Mathematical Physicist

A Legacy Built on Numerical Solutions

John Crank, a renowned mathematical physicist, is best known for his groundbreaking work on the numerical solution of partial differential equations, particularly in the field of heat conduction problems. His collaboration with Phyllis Nicolson led to the development of the Crank-Nicolson method, a pivotal contribution to the world of mathematics.

Early Life and Education

Born on February 6, 1916, in Hindley, Lancashire, England, Crank was the son of a carpenter's pattern maker. He pursued his academic interests at Manchester University, where he earned his BSc and MSc degrees between 1934 and 1938. Notably, he was a student of the esteemed Lawrence Bragg and Douglas Hartree. In 1953, Manchester University awarded him a DSc, further solidifying his academic credentials.

War Efforts and Early Career

During World War II, Crank worked on ballistics, applying his mathematical expertise to support the war effort. Following the war, he joined Courtaulds Fundamental Research Laboratory as a mathematical physicist, where he spent 12 years (1945-1957) honing his skills and making significant contributions to the field.

Academic Leadership and Legacy

In 1957, Crank was appointed as the first Head of Department of Mathematics at Brunel College in Acton. He went on to serve two terms as Vice-Principal of Brunel, leaving an indelible mark on the institution. Upon his retirement in 1981, he was granted the title of Professor Emeritus, a testament to his dedication and achievements.

The Crank-Nicolson Method

Crank's most notable contribution to mathematics is the Crank-Nicolson method, developed in collaboration with Phyllis Nicolson. This innovative approach to solving partial differential equations has had a profound impact on various fields, including heat transfer, fluid dynamics, and computer simulations.

A Passion for Gardening and Family

Away from the world of mathematics, Crank was an avid gardener. As a retirement gift to Brunel University, he established the John Crank Garden, a beautiful oasis that continues to thrive. Crank was married to his loving wife, Joan, for 63 years until her passing in 2005. They were survived by their two children, a testament to their enduring love and legacy.

Lifetime Achievements and Honors

Throughout his illustrious career, Crank received numerous accolades for his contributions to mathematics and education. His dedication to his craft and his students has inspired generations of mathematicians and scientists.
