A. Martin Eiband NASA Engineer

A. Martin Eiband, 88, a NASA research engineer who is credited with inventing diagrams that help engineers determine the probability of survival and injury in crashes, died March 29 after a heart attack at Doctors Community Hospital in Lanham. He was a New Carrollton resident.

In 1959, Mr. Eiband developed what came to be called "Eiband Curves," which depict the magnitude of acceleration vs. the duration of uniform acceleration, plotted on a logarithmic scale. When restrained in an accelerating vehicle, the human body behaves in predictable ways, and Mr. Eiband's work showed how to calculate those reactions and enabled others to create better safety measures for people in aircraft and vehicles on the ground.

Born Anthony Martin Eiband in Auburn, N.Y., he graduated from high school then worked during World War II for Lockheed Overseas in Belfast. After the war ended, he graduated from Purdue University in 1951, and went to work for the National Advisory Committee on Aeronautics, a predecessor of NASA. Shortly after NASA was formed in 1958, Mr. Eiband switched to that agency. He worked there until 1983, then moved to the private sector as an engineer with EER Inc. before retiring in 1988.

Mr. Eiband volunteered for more than 50 years with the National Capital Area Council of the Boy Scouts of America. An Eagle Scout, he also was a recipient of the Scouts' Silver Beaver Award. Mr. Eiband was also twice president of the New Carrollton Men's Club and spent more than a decade as head of the Ballroom Dance Club for the Maryland Park and Planning Commission.

Survivors include his wife of 63 years, Marian W. Eiband of New Carrollton; three children, David M. Eiband of Vail, Ariz., Cheryl R. Russial of Bethel Park, Pa., and Jason D. Eiband of San Francisco; a brother; and a granddaughter.

Samuel Kotz Statistician

Samuel Kotz, 79, a statistics professor and editor of the Encyclopedia of Statistical Sciences, died March 16 at his home in Silver Spring. He had pulmonary fibrosis.

At the time of his death, Dr. Kotz was a research professor at George Washington University, where he had worked since 1997. He previously taught at the University of Maryland.

Dr. Kotz wrote or edited more than a dozen books, including the nearly 10,000-page encyclopedia. Another book, "Leading Personalities in Statistical Sciences," presented Florence Nightingale as a notable statistician for developing a system to track mortality rates during the Crimean War.

Dr. Kotz was born in Harbin, China, to a Jewish family that left Russia after the Russian Revolution. He studied electrical engineering at the Harbin Institute of Technology and in 1949 moved to Israel. After serving in the Israeli air force, he received a master's degree in mathematics from Hebrew University in Jerusalem. He came to the United States in the late 1950s, received a doctorate in mathematics from Cornell University in 1960 and became a U.S. citizen in the early 1970s.
