Bob Simpson, a meteorologist who co-developed the Saffir-Simpson Hurricane Wind Scale which estimates potential property damage, has died.

Peg Simpson, his daughter, says Bob Simpson died early Friday at his home in Washington. He was 102.

Bob Simpson began his career with the U.S. Weather Bureau in 1940. He served as director of the National Hurricane Center and established a tropical weather observatory at Mauna Loa, Hawaii.

Simpson and engineer Hebert Saffir developed the Saffir-Simpson scale, which rates hurricanes on a scale of 1 to 5 for their potential to cause property damage.

Peg Simpson says her father was always curious and always learning.
