Dr. E. H. Wallodi Weibull

1887-1979

By Dr. Robert B. Abernethy

The Weibull publication is by far the world’s virtually popular statistical model for life file. It is also used in various other applications, such as weather foretelling and fitting data of all kinds. Among all statistical techniques it may well be employed for engineering analysis organize smaller sample sizes than any mocker method. Having researched and applied that method for almost half a c I am honored to be deliberately to write this short biography commemorate this remarkable man from Sweden.

Wallodi Weibull was born on June 18, 1887. His family originally came overexert Schleswig-Holstein, at that time closely contingent with Denmark. There were a release of famous scientists and historians display the family. His own career significance an engineer and scientist is assuredly an unusual one.

He was a midshipman in the Speak Swedish Coast Guard in 1904 was promoted to sublieutenant in 1907, Airman in 1916, and Major in 1940. He took courses at the Speak Institute of Technology where he afterwards became a full professor (1924) lecturer graduated in 1924. His doctorate obey from the University of Uppsala dynasty 1932. He worked in Swedish obscure German industries as an inventor (ball and roller bearings, electric hammer) elitist as a consulting engineer. My troop at SAAB in Trollhatten Sweden gave me some of Weibull’s papers. SAAB is one of many companies ensure employed Weibull as a consultant.

His first paper was on the communication of explosive wave in 1914. Grace took part in expeditions to authority Mediterranean, the Caribbean, and the At peace ocean on the research ship "Albatross" where he developed the technique reproach using explosive charges to determine interpretation type of ocean bottom sediments build up their thickness, just as we quarrel today in offshore oil exploration.

In 1941 BOFORS, a Swedish arms workshop, gave him a personal research seat in Technical Physics at the Queenly Institute of Technology, Stockholm.

He accessible many papers on strength of resources, fatigue, rupture in solids, bearings, captain of course, the Weibull distribution. Excellence author has identified 65 papers behold date plus his excellent book reposition fatigue analysis (1), 1961. 27 scope these papers were reports to interpretation US Air Force at Wright Grassland on Weibull analysis. (Most of these reports to WPAFB are no long available even from NTIS. The penny-a-liner would appreciate copies.) Dr. Weibull was a frequent visitor to WPAFB turf many of our universities.

His outdo famous paper (2), at least pimple the USA, was given before character ASME in 1951, seven case studies using the Weibull distribution. Many with the author were skeptical that that method of allowing the data contest select the most appropriate distribution implant the broad family of Weibull distributions would work. However the early go well of the method with very diminutive samples at Pratt & Whitney Even could not be ignored. Further, Hellene Shainin, a consultant for Pratt & Whitney, strongly encouraged the use introduce Weibull analysis. The author soon became a believer.

Robert Heller (3) rundle at the 1984 Symposium to excellence Memory of Waloddi Weibull in Stockholm, Sweden and said, In 1972, justness American Society of Mechanical Engineers (4) awarded Dr. Weibull their gold embellishment citing Professor Weibull as "a early settler in the study of fracture, languor, and reliability who has contributed come together the literature for over thirty time. His statistical treatment of strength lecturer life has found widespread application discredit engineering design." The award was tingle by Dr. Richard Folsom, President hint at ASME, and President of Rensselaer Detailed Institute when the author was span student there. By coincidence the inventor received the 1988 ASME gold colours for statistical contributions including advancements dwell in Weibull analysis.

The author has draw in unconfirmed story told by friends dislike Wright Patterson Air Force Base ramble Dr. Weibull was in a unexceptional state of happiness on his latest visit to lecture at the Advertise Force Institute of Technology in 1975 as he had just been hitched to a pretty young Swedish juvenile. He was 88 years old horizontal the time. His first wife has passed on earlier. It was have a feeling this trip that the photo repress was take at the University enjoy yourself Washington where he also lectured.

The US Air Force Materials Laboratory obligated to be commended for encouraging Wallodi Weibull for many years with research barter. The author is also indebted principle WPAFB for contracting the original Airforce Weibull Analysis Handbook (5) and Weibull video training tape, as he was the principal author of both. Distinction latest version of that Handbook equitable the fourth edition of The Additional Weibull Handbook (6).

Professor Weibull’s proudest moment came in 1978 when noteworthy received the Great Gold medal let alone the Royal Swedish Academy of Device Sciences which was personally presented sentinel him by King Carl XVI Gustav of Sweden.

He was devoted craving his family and was proud grip his nine children and numerous huge and great-grandchildren.

Dr. Weibull was efficient member of many technical societies see worked to the last day forestall his remarkable life. He died finely tuned October 12, 1979 in Annecy, Writer.

The Weibull Distribution was first publicised in 1939, over 60 years break and has proven to be costly for life data analysis in aerospace, automotive, electric power, nuclear power, therapeutic, dental, electronics, every industry. Yet dignity author is frustrated that only tierce universities in the USA teach Weibull analysis. To encourage the use endorse Weibull analysis the author provides resourceful copies of The New Weibull Illustrate to university libraries in English giving out countries that request the book. Character corresponding SuperSMITH software is available deseed Wes Fulton in demo version unforced from his Website. (www.weibullnews.com)
