Between 1939 and 1945, he worked at the then Kaiser Wilhelm Institute for Medical Research in Heidelberg, where he conducted research on poison gases under the supervision of Richard Kuhn (co-discoverer of Soman).[1] In 1948, he joined Henkel as a chemist in product development. From 1949 to 1956, Konrad Henkel was Head of Product Development at Henkel and finally became a member of the management board in 1956.[citation needed]
After the early death of his brother Jost[2] in 1961, Konrad Henkel became chairman of the management board of the company, which he then transferred to a KGaA in 1975. In 1980, Konrad Henkel retired from corporate management and moved to the supervisory board, which he chaired between 1980 and 1990. He handed over the chairmanship of the management board to Prof. Dr. Helmut Sihler, the first non-family manager to head the company. Between 1976 and 1990, Konrad Henkel was also Chairman of the Shareholders' Committee of Henkel KGaA, and from 1990 to 1999 Honorary Chairman of the Henkel Group. His time as Chairman of the Shareholders' Committee and the supervisory board coincided with the Companies IPO in 1985. Konrad Henkel died in his home town of Düsseldorf in 1999 at the age of 83.[citation needed]
From 1972 to 1973, Henkel was President of the German Chemical Industry Association (VCI), from 1967 to 1990 Chairman of the Industrie-Club Düsseldorf, and from 1982 to 1991 Chairman of the supervisory board of Degussa AG.[citation needed]
Controversy
Konrad Henkel was involved in a party donation scandal in the 1980s. He was accused of having donated 4.22 million Marks to the CDU/CSU and FDP, therefore evading 1.896 million Marks in taxes. The Bonn public prosecutors office issued a fine for 3.5 million Marks, which Henkel contradicted. As a result, legal proceedings were initiated against him at the end of 1988. These proceedings were discontinued in January 1990 due to formal errors in the original fine.[3]
Henkel had three daughters Andrea, Renate and Karin from his first marriage[2][5] and a son, Christoph Henkel with his second wife Gabriele Henkel (1955), who inherited his shares in the company.[6]
