Hans-Joachim Timpe (*September 12th,1939; Halle/Saale) is a German chemist in the area of photochemistry and photopolymerisation. Hans was born in September 1939 as first of two children. His father was a teacher and did military service when Hans was born. From 1945 to 1953 Hans completed his compulsory schooling in three different school, two of them in tiny villages. After this he went to the Extented Secondary School in East Germany. During the last year Hans was prepared for his university studies in Soviet Union (Russia) were he also finished his Abitur ("certificate of general qualification for university entrance“). However, due to some health issues Hans decided to study chemistry at the Technical University Dresden (TU Dresden) from 1957 to 1962.

In 1962 Hans finished his Master thesis in organic chemistry (Diplom-Chemiker/MSc). After this Hans followed Prof. Dr. Heinz G. O. Becker from the TU Dresden to the Technical University Leuna-Merseburg (THLM) where he finished his PhD (Dr. rer. nat.) in organic chemistry in 1966. He started his academic career as junior lecturer at THLM, continued there as senior scientific assistent, was nominated as assistant professor at the Institute of Organic Chemistry at THLM after his habilitation (1980; Dr. habil.) and finally appointed as full professor of organic chemistry. Some of his studies and publications were done in cooperation with international partners like Prague Institute of Chemical Technology, Slovak Institute of Technology, Ufa State Oil Technology, University of Wroclaw and Universite de Haut-Alsace.

Hans spent 10 months of postgradual studies at Leningrad Institute of Technology (today St. Petersburg Institute of Technology) in the group of Prof. Dr. Andrej V. El’tsov in 1973/74 and three months at the Columbia University New York in the group of Prof. Dr. Nicolas Turro in 1983.

At THLM Hans gave lectures in organic chemistry, stereo chemistry, photochemistry and intellectual properties (patents). He was contributing author to chemical books like „Reaktionsverhalten und Syntheseprinzipien“ (in German, 4 editions), „Einführung in die Photochemie“ (in Russian and German), „Photopolymere“, „Tabellenbuch brennbarer und gefährlicher Stoffe“, „Technical Applications of Photochemistry“ and Polymer Science and Technology“. Four years Hans was the Chairman of the chemical faculty of THLM which was the largest in Eastern Germany at this time and from 1986 to 1990 Director of the Institute of Photochemistry of this faculty.

Hans is leading author in more than 400 written and 259 oral papers. Furthermore, he published several reviews „Heterocyclic Chemistry“, Topics in Current Chemistry“, „Radiation Curing in Polymer Science and Technology“, Functional Polymers“ and „Photochemische Reaktionen“ (in Russian). Last but not least, Hans was the main inventor in about 25 patents in East Germany in cooperation with industry there. Hans was supervisor of 18 MSc thesis (Diplom-Chemiker) and 14 doctoral thesis during his university career.

In September 1991 Hans finished his academic career and switched to industry. He joined the research and development department (R&D) as Head of Central Laboratory of Polychrome company in Osterode (today Kodak). Together his team he developed negative lithographic printing plates. One of these can be polymerized by lasers in near infrared (NIR) region. Two of these has been produced and used worldwide. During his industrial career Hans became inventor and co-inventor of more than 35 German and international patents. Furthermore, he supported two PhD thesis and one BSc thesis.

In 2005 Hans retired and enjoyed life by traveling together his wife worldwide with his caravan.
