Timothy P. Marshall
American engineer

Timothy Patrick Marshall (born October 17, 1956) is an American structural and forensic engineer as well as a meteorologist, concentrating on damage analysis, particularly that from wind, hail, and other weather phenomena. He is also a pioneering storm chaser and was editor of Storm Track magazine.
Early life and education
Marshall was born to Charles and Catherine Marshall in Evergreen Park near Chicago, in 1956 and raised in Oak Lawn, then in Oak Brook. Oak Lawn was heavily damaged during the historic 1967 Oak Lawn tornado outbreak of April 21, 1967, when he was 10 years old. The F4 "Oak Lawn tornado" touched down about 4 mi (6.4 km) west of his home and killed 33 in town, including some of his classmates. This experience served to strengthen his interest in meteorology, and he focused his studies on tornadoes.
Marshall attended Northern Illinois University (NIU) in DeKalb, attaining a B.S. degree in geography with a concentration in meteorology in 1978. As an undergraduate student there, he and classmates surveyed some tornado damage paths of the 1974 Super Outbreak during an informal trip to the National Climatic Data Center (NCDC) to collect severe weather data. Later, he and fellow students visited the National Severe Storms Forecast Center (NSSFC) and obtained a large collection of materials the library was dumping, which formed the basis of his own library.
Marshall went to Texas for graduate school, seeing his first tornado a few hours after entering the state.

Why this record matters
The phrase “american engineer” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Sep 1, 2026. The linked authority identifier is Q7807444. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1956, 1967, 1978 and 1974.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
