Wade H. Pugh III, 58, who had been a math professor at Montgomery College in Rockville since 1998, died April 27 at Johns Hopkins Hospital in Baltimore of complications from septic shock.

Mr. Pugh moved to Silver Spring from Tampa in the mid-1980s to start a tutoring business called A+ Tutoring, which he closed a few years later. He also taught math at the District’s Mount Vernon College, which later merged with George Washington University.

While teaching at Montgomery College, he operated a tutoring business out of his home called Probastat that specialized in probability and statistics.

Wade Hampton Pugh III was a native of Coatesville, Pa. In 1973, he earned an associate’s degree from what is now Potomac State College of West Virginia University. He received a bachelor’s degree in 1975 from Shepherd University in West Virginia and a master’s degree in economics from West Virginia University in 1978.

Mr. Pugh was a member of Christ Lutheran Church of the Deaf in Silver Spring.

Survivors include his wife of 12 years, Lisa Wellander Pugh of Silver Spring; and a sister.
