With roots stretching back two centuries, KIT has played a pivotal role in shaping science, technology, and society. This article explores the history, academic offerings, research endeavors, and student life that define this esteemed institution.

Historical Overview: From Polytechnische Schule to KIT

The story of KIT is one of continuous evolution, reflecting its commitment to adapting to the changing needs of society and industry.

The Early Years: A Focus on Practical Skills

Founded in 1825 as the Polytechnische Schule, the institution was initially designed as a center for technical and vocational education. This emphasis on practical skills and applied knowledge distinguished it from other universities of the time, which prioritized classical studies and theoretical knowledge.

Expansion and Transformation: Embracing Scientific and Engineering Disciplines

Throughout the 19th century, the Polytechnische Schule gradually expanded its curriculum to include more advanced scientific and engineering disciplines. This expansion reflected the increasing importance of these fields in a rapidly industrializing world. The institution also placed greater emphasis on research and development, seeking to contribute directly to technological innovation.

The 20th Century: Reconstruction, Modernization, and Research Expansion

The 20th century saw the university play a crucial role in Germany's reconstruction and modernization after World War II. It provided skilled engineers and scientists to rebuild the nation's infrastructure and economy. During this period, the university also expanded its research capabilities, establishing numerous specialized institutes and centers dedicated to cutting-edge scientific inquiry.

The Merger: Creating a "University of Excellence"

In 2009, the University of Karlsruhe merged with the Forschungszentrum Karlsruhe (Karlsruhe Research Centre) to form the Karlsruhe Institute of Technology (KIT). This merger aimed to create a unique institution that seamlessly integrates research and education, fostering a culture of innovation and entrepreneurship. KIT was conceived as a "university of excellence," capable of competing with the world’s leading research universities. The merger combined the university’s academic strengths with the research center’s vast scientific resources, creating a powerhouse of knowledge and innovation. The Campus Nord (Campus North), the former Forschungszentrum, was founded in 1956 as Kernforschungszentrum Karlsruhe (KfK) (Karlsruhe Nuclear Research Centre). Initial activities focused on Forschungsreaktor 2 (FR2), the first nuclear reactor built by Germany. With the decline of nuclear energy activities in Germany, Kernforschungszentrum Karlsruhe directed its work increasingly towards alternative areas of basic and applied sciences. This change is reflected in the change of name from Kernforschungszentrum Karlsruhe to Forschungszentrum Karlsruhe with the subheading Technik und Umwelt (technology and environment) added in 1995. Campus Nord is the site of the main German national nuclear engineering research centre and the Institute for Transuranium Elements.

Since 1902, the university has also been referred to as the Fridericiana, an homage to Grand Duke Friedrich I of Baden, who officially elevated the University of Karlsruhe to Hochschule status - making it a fully-fledged university in the late 19th century.

Polymer Science at Karlsruhe: A Rich History

It might not be well known that the foundation of polymer science has very strong roots in Karlsruhe. Therefore, the intention of this short historical article is to display this rich history and especially mention people and research groups who worked in Karlsruhe in the area of polymer science over the last approximately 125 years. Several aspects of the history of polymer science in Karlsruhe are presented. The first polymerization of styrene might have taken place in Karlsruhe in or before 1900 in the group of Carl Engler and was published by himself and his assistant A. Kronstein between 1897 and 1902. Later, the entire Ph.D. thesis of Mr. Lautenschläger (finished 1913) focused on polymerization. Very famous polymer scientists, specifically Hermann Staudinger, Leo Ubbelohde, Hermann Mark, and Werner Kuhn, all worked as professors in Karlsruhe, and contributed substantially to polymer science in these early days.

Key Figures in Polymer Science at Karlsruhe

Carl Engler: The first person in Karlsruhe who can be related to polymer science is Prof. Carl Engler (*1842-†1925), who held a chair of Chemical Technology. His research had a focus on mineral oils, and he developed a viscosimeter, the “Engler viscosimeter”, to characterize mineral oils. These mineral oils often contained molecules with double bonds. He was further interested in the polymerization of styrene and, more generally, molecules containing C═C double bonds. Carl Engler was also a board member of BASF since 1903 and acted as a mentor for two young and very ambitious professors around 1910 at Karlsruhe: Fritz Haber, born 1868, and Hermann Staudinger, born 1881. Prof. C. Engler fostered Staudinger's relations to industry, specifically to BASF, and introduced him to polymerization. Hermann Staudinger, on the other side, helped Prof. C. Engler, already 71 years of age at the time, by supervising Ludwig (in short: Leo) Carl Lautenschläger during his Ph.D. to polymerize olefinic monomers. The polymerizations were performed both with and without peroxides as apparent initiators. Lautenschläger studied the kinetics of these polymerization reactions.
Leo Ubbelohde: In 1910, Leo Ubbelohde (*1876-†1964) conducted a habilitation in Chemical Technology in Karlsruhe as Carl Engler had asked him to move from Berlin to Karlsruhe. Habilitation is the German equivalent of an assistant professorship conducted under the supervision of a full professor, in his case Prof. Hans Bunte. Leo Ubbelohde was afterwards assistant and lecturer (German: Privatdozent) and received a professor's position in 1911 in Technical Chemistry in Karlsruhe, and took a position in 1933 at TU‐Berlin as a professor since others were forced out. His science was centered around petroleum. He is very well known for the Ubbelohde viscometer, which is still in use today in many laboratories around the world to study low viscosity solvents and dilute polymer solutions. At KIT, we still use it within our current polymer laboratory course. The experimental beauty is to dissolve a known mass of polymer and measure, with a simple stopwatch, the time needed for a specific volume of the solution to pass through a defined capillary, using a setup that compensates for pressure changes. The increase in the solution viscosity, as compared to the pure solvent, is then calculated from the elapsed time and allows the determination of the molecular weight of the dissolved polymer according to the Mark-Houwink equation.
Hermann Staudinger: The most well‐known polymer scientist from Karlsruhe is Hermann Staudinger (*1881-†1965). He introduced the concept of macromolecules and received the Nobel Prize in chemistry in 1953 for his discoveries in the field of macromolecular chemistry. Staudinger was first trained as an organic chemist in Halle/Germany. In 1907, Staudinger finished his habilitation in Strasbourg, where he focused on organic chemistry, and his research included the study of ketenes, diazo compounds, and the use of oxaylchloride, just to give some examples. Directly in 1907, he received his first professorship in Karlsruhe. In 1912, he took a chaired professor position at ETH Zurich, Switzerland, and finally moved to Freiburg, Germany, in 1926. The influence of Carl Engler, from 1907 on, first led him to synthesize butadiene and isoprene, and thus led to the work on unsaturated monomers. The chemical reactivity of these two monomers, but also limonene, myrcene, and styrene, just to mention other investigated compounds, was very interesting to him. Please note that at the time of Staudinger in Karlsruhe (1907-1912), Fritz Haber was an appointed professor, and Leopold Ruzicka was a Ph.D. student of Staudinger. All three scientists performed research in the same faculty at Karlsruhe, and all of them received, on independent topics, a Nobel prize.
Hermann Franz Mark: The name Hermann Franz Mark (*1895-†1992, engl.: Herman Francis Mark) is familiar to many polymer scientists. Less known is his relation to Karlsruhe. Hermann Mark originated from Vienna, where he earned a Ph.D. in chemistry and taught Pauling about X‐rays and did experiments for Einstein. Fritz Haber invited him to work in Berlin at the Kaiser‐Wilhelm‐Institute, the predecessor of the Max‐Planck‐Institute. Due to an offer from Kurt Heinrich Meyer, he worked at the IG Farben in Ludwigshafen from 1927 to 1932, applying X‐ray diffraction to macromolecules and helped the company to understand and commercialize polystyrene, polyvinylchloride, and polyvinyl alcohol. To foster relations between BASF and a nearby university, Karlsruhe and Ludwigshafen are only 70 km apart, Hermann Mark finished his habilitation in Karlsruhe in 1927 and held an extraordinary professorship thereafter.
Werner Kuhn: Werner Kuhn (*1899-†1963) is well known in polymer science for the concept of the Kuhn length, a measure of persistence and a statistical quantity towards an ideal state. Werner Kuhn was Swiss by nationality and completed a Ph.D. at the ETH Zürich and a postdoc with Niels Bohr. Werner Kuhn was an associate professor in Karlsruhe from 1930 to 1936 and published in Karlsruhe his famous work: “Über die Gestalt der fadenförmigen Moleküle in Lösungen” [29], translated to “On the shape of strand‐like molecules in solution” in 1934.
