Early in the s the Dantzig family moved from Baltimore to Washington. His mother became a linguist at the Library of Congressand his father became a math tutor at the University of Maryland, College Park.

He earned his master's degree in mathematics from the University of Michigan in After a two-year period at the Bureau of Labor Statistics, he enrolled in the doctoral program in mathematics at the University of California, Berkeleywhere he studied statistics under Jerzy Neyman.

Air Force Office of Statistical Control. Inhe returned to Berkeley to complete the requirements of his program and received his Ph. A year later, the Program george johnson science writer Operations Research became a full-fledged department. Later he became the C. Criley Professor of Transportation Sciences at Stanfordand kept going, well beyond his mandatory retirement in Dantzig was the recipient of many honors, including the first John von Neumann Theory Prize inthe National Medal of Science in[5] an honorary doctorate from the University of Maryland, College Park in Dantzig Prizebestowed every three years since on one or two people who have made a significant impact in the field of mathematical programming.

Dantzig died on May 13,in his home in Stanford, Californiaof complications from diabetes and cardiovascular disease. He was 90 years old. Based on his work tools are developed "that shipping companies use to determine how many planes they need and where their delivery trucks should be deployed.

The oil industry long has used linear programming in refinery planning, as it determines how much of its raw product should become different grades of gasoline and how much should be used for petroleum-based byproducts.

It is used in manufacturing, revenue management, telecommunications, advertising, architecture, circuit design and countless other areas". Near the beginning of a class for which Dantzig was late, professor Jerzy Neyman wrote two examples of famously unsolved statistics problems on the blackboard.

When Dantzig arrived, he assumed that the two problems were a homework assignment and wrote them down. According to Dantzig, the problems "seemed to be a little harder than usual", but a few days later he handed in completed solutions for the two problems, still believing that they were an assignment that was overdue.

Years later another researcher, Abraham Waldwas preparing to publish an article that arrived at a conclusion for the second problem, and included Dantzig as its co-author when he learned of the earlier solution.

Over time Dantzig's name was removed, and facts were altered, but the basic story persisted in the form of an urban legend and as an introductory scene in the movie Good Will Hunting.

Linear programming arose as a mathematical model developed during World War II to plan expenditures and returns in order to reduce costs to the army and increase losses to the enemy. It was kept secret until Postwar, many industries found its use in their daily planning. The founders of this subject are Leonid Kantorovicha Russian mathematician who developed linear programming problems inDantzig, who published the simplex method inand John von Neumannwho developed the theory of the duality in the same year.

Dantzig's original example of finding the best assignment of 70 people to 70 jobs exemplifies the usefulness of linear programming. The computing power required to test all the permutations to select the best assignment is vast; the number of possible configurations exceeds the number of particles in the universe.

However, it takes only a moment to find the optimum solution by posing the problem as a linear program and applying the Simplex algorithm.

The theory behind linear programming drastically reduces the number of possible optimal solutions that must be checked. Rich in insight and coverage of significant topics, the book quickly became "the bible" of linear programming. Books by George Dantzig: Notes on linear programming.
