Timeline

1963

In 1963 along with his father Lester R. Ford, he published an innovative textbook on calculus. For a given function f and point x, they defined a frame as a rectangle containing (x, f(x)) with sides parallel to the axes of the plane (page 9). Frames are then exploited to define continuous functions (page 10) and to describe integrable functions (page 148).

1956

In 1956, Ford developed the Bellman–Ford algorithm for finding shortest paths in graphs that have negative weights, two years before Richard Bellman also published the algorithm.

1954

Ford's paper with D. R. Fulkerson on the maximum flow problem and the Ford–Fulkerson algorithm for solving it, published as a technical report in 1954 and in a journal in 1956, established the max-flow min-cut theorem. In 1962 they published Flows in Networks with Princeton University Press. According to the preface, it "included topics that were purely mathematically motivated, together with those that are strictly utilitarian in concept." In his review, S.W. Golomb wrote, "This book is an attractive, well-written account of a fairly new topic in pure and applied combinatorial analysis." As a topic of continued interest, a new edition was published in 2010 with a new foreword by Robert G. Bland and James B. Orlin.

1927

Lester Randolph Ford Jr. (September 23, 1927 – February 26, 2017) was an American mathematician specializing in network flow problems. He was the son of mathematician Lester R. Ford Sr.

Lester was born in Houston, Texas on September 23, 1927. He learned to play piano and the flute and was frequently heard whistling. For higher education he considered Harvard and Oberlin Conservatory, but chose the University of Chicago which provided him a scholarship. He earned his bachelor's degree in 1949 and a masters in 1950. Ford continued his studies at University of Illinois at Urbana-Champaign where he earned a Ph.D. in mathematics in 1953.
