Biographical Note

Harry J. Haon II (1901-1989) and his son Harry J. Haon III (1934-2013) were chemists and lifetime employees of E.I. du Pont de Nemours & Company, and both came to specialize in sales and marketing.

Harry J. Haon, II was born on October 29, 1901 in Orville Township, New Jersey and spent his career with E.I. du Pont de Nemours & Company. He began working in DuPont Company laboratories part-time during summers from 1913 until 1922. Following college he joined DuPont full time in 1924 as a chemist at the Parlin, New Jersey laboratory where he was introduced to the fabrics and finishes industry. After two years Haon advanced to the level of laboratory supervisor, and in 1927 he became Supervisor of Technical Sales. Understanding the value of Haon's science and sales background, DuPont assigned him to its European office in London as a representative for technical information where he worked for seven years.

From 1936 until the United States became involved in World War II, Haon worked in the U.S. in the Fabrics and Finishes Department of DuPont, first as Sales Development Supervisor, then Assistant Manager of Industrial Sales, and later Manager of Field Research. During the war, he was promoted to Technical Manager in DuPont's Development Division, Electrochemical Department. In May 1952 Haon was again promoted, this time to the position of Special Assistant to J. Warren Kinsman, DuPont Vice Presidential Advisor for Sales and Advertising. In April 1954 Haon became the Manager of Sales Training section of DuPont's Employee Relations Department. He was promoted again in October of that year to the Foreign Relations Department in the position of Manager of the European Office in London, England, until he retired in August, 1962. He died on January 9, 1989 at the age of 87.

Harry J. Haon, III was born in London, England in August 2, 1934. He was educated at Tower Hill School in Wilmington, Delaware and received a Bachelor of Science degree in engineering from Princeton University in 1956. Haon began his employment with the DuPont Company as a Product Technologist in the Marketing Section of the Teflon group with responsibility for the development of FEP (fluorinated ethylene propylene) resins. Later Haon joined the Technical Services Laboratory of the Polychemicals Department doing field service work on extrusion of Teflon FEP resins. Haon also held positions in fluorocarbon sales and marketing (1961-1965); supervisor for the production of Adiponitrile in Victoria, Texas (1966-1968); marketing specialist for Tefzel fluorocarbons (1968-1969); assistant district manager for Teflon in New York City (1969-1970); New York district manager for Teflon (1970-1972); marketing manager for filaments and straps (1972-1978); marketing manager for Permasep products (1978-1980) manager Aldyl piping systems (1980-1981); manager Aldyl piping systems and Teflon heat exchangers (1981-1985); on loan to the corporate marketing program (1985-1986); Principal Consultant to Fabric and Finishing Products Department, supporting sporting goods, explosives and engineered products (1986-1989). Haon died at St. Francis Hospital in Wilmington on January 15, 2013 at the age of 78 years.

Scope and Content

The Harry J. Haon family papers are a collection of DuPont Company correspondence, meeting notes and minutes, drawings, maps, journal articles, publications, and once-classified documents about products. These records document various aspects of the DuPont Company from the 1920s through the 1980s, including management issues, marketing strategies, product information, corporate training, expansion planning, and the creation and growth of the company's European market.

The collection of records thoroughly document the careers of two generations of DuPont managers. The papers of Harry Haon II include valuable information about DuPont Europe and the company's London office before World War II and for several decades during the post-war period. His papers also document DuPont's postwar plans for expansion, particularly in southern California.

Harry Haon III's papers contain marketing materials for Aldyl piping and Teflon, information about the global gas pipe industry, and records documenting management philosophy in the 1970s and 1980s.

Both of the Haons' records include teaching materials for newly-hired marketing managers, sales personnel, and other employees in leadership positions.
