# Betty W. Holz

Betty Rose Weber Holz (September 15, 1919 – September 3, 2005) was an American mathematician who worked for the United States Army.

## Early life and education

Betty Rose Weber was born in Florida, the daughter of William Wilson Weber and Rosalie I. Langford Weber. Her father was a math professor.
Weber earned a bachelor's degree in mathematics from Columbia College in 1940. She completed a master's degree in mathematics at the University of South Carolina in 1949, and pursued further graduate studies at the University of North Carolina and at American University. As a student, she won a medal for excellence in piano performance.

## Career

Holz taught mathematics at the University of South Carolina, and was an engineer with Melpar, a defense contractor. Beginning in 1954, she was an analyst for the United States Army's Operations Research Office, later the Research Analysis Corporation, in Washington, D.C. In 1961 she and Edward M. Girard represented the US at the American-British-Canadian Ad Hoc Working Group on War Gaming and Simulation when it met in London. In the 1960s and 1970s, she helped to develop ELIM (the Enlisted Loss Inventory Model) and COMPLIP (Computation of Manpower Programs Using Linear Programming), early computer programs for modeling military manpower and logistics.
Holz was a member of Phi Beta Kappa, the Society for Industrial and Applied Mathematics, the Operations Research Society of America, and the American Mathematical Society.
