Humboldt University of Berlin alumni

Daniel Vorländer (11 June 1867 – 8 June 1941) was a German chemist who synthesized most of the liquid crystals known until his retirement in 1935.
Vorländer was born in Eupen in Rhenish Prussia. He studied chemistry at Kiel, Munich, and Berlin, after which he became a professor at University of Halle-Wittenberg.
Vorländer applied his knowledge of molecular structure to select those exhibiting the crystalline liquid state. In particular a linear molecular geometry was conductive. "Over the years Vorländer and his students synthesized hundreds of liquid crystalline compounds. An interesting discovery was that amongst the slimy liquid crystals were many soap and soap-like compounds." (Dunmur & Sluckin p 48)
Vorländer served as a volunteer during World War I, during which he received the Iron Cross. He died in Halle.

Paul Theodor Range (1 May 1879 in Lübeck – 29 August 1952 in Lübeck) was a German geologist and naturalist.
He studied natural sciences at the universities of Würzburg and Leipzig, receiving his doctorate in 1903. From 1906 to 1914 he worked as a government geologist in German South-West Africa, and afterwards performed scientific studies in the Sinai Peninsula. From 1921 he gave lectures in geology at the University of Berlin, becoming an associate professor in 1934. In 1936, he was named president of the Deutschen Geologischen Gesellschaft.Range is commemorated in the scientific name of the Namib sand gecko (Pachydactylus rangei), which was described as a species new to science by herpetologist Lars Gabriel Andersson in 1908.

Karl Holl (15 May 1866 – 23 May 1926) was a professor of theology and church history at Tübingen and Berlin and is considered one of the most influential church historians of his era.

Ferdinand Adolph Theophil Hueppe (24 August 1852 – 15 September 1938) was a German physician, bacteriologist and hygienist. From 1900 to 1904, he was the first Deutscher Fußball-Bund (DFB, German Football Association) president.

Johannes Fabry (1 June 1860, in Jülich – 29 June 1930, in Dortmund) was a German dermatologist.
He studied medicine at the universities of Bern and Berlin, receiving his doctorate in 1886. Following graduation he trained in dermatology under Joseph Doutrelepont at the University of Bonn and with Hugo Ribbert in Zürich. From 1889 to 1929 he was chief medical officer of the Skin Clinic at the Dortmund municipal hospital, which under his guidance, became a leading center for dermatology.His name is associated with "Fabry disease", a rare, inherited metabolic disease characterized by telangiectatic skin lesions, kidney failure and disorders of the cardiovascular, gastrointestinal, and central nervous systems. In 1898 he described dermatological features of the disease in a 13-year-old boy, naming the condition "purpura haemorrhagica nodularis". The disease is also called "Anderson-Fabry disease", named along with British surgeon William Anderson, who independent of Fabry, reviewed the progression of the disease over nearly 20 years in a 39-year-old patient.

Alexander Ellinger (17 April 1870 in Frankfurt am Main – 26 July 1923 in Frankfurt am Main) was a German chemist and pharmacologist.
From 1887 he studied chemistry at the University of Berlin under August Wilhelm von Hofmann and at the University of Bonn as a pupil of August Kekulé. Afterwards, he studied medicine at the University of Munich, followed by work as an assistant in the institute of pharmacology at the University of Strasbourg. In 1897 he became an assistant to Max Jaffé in the laboratory of medicinal chemistry and experimental pharmacology at the University of Königsberg. In 1914 he was appointed professor of pharmacology at the newly established University of Frankfurt.He is remembered for his extensive biochemical research of several amino acids, especially tryptophan. In 1904 he isolated kynurenic acid from the urine of dogs that had been fed tryptophan. His other work included studies on the water exchange between body tissues and blood, on the formation on lymph, and with chemist Karl Spiro, he conducted investigations of blood coagulation.

Max Alsberg (16 October 1877 – 11 September 1933) was a famous criminal lawyer of the Weimar Republic.
Alsberg worked primarily as a criminal defense lawyer; he defended Karl Helfferich in 1920 and Carl von Ossietzky in 1931. He also wrote plays (Voruntersuchung in 1927, and Konflikt). His best known contribution to legal science is the handbook Der Beweisantrag im Strafprozess.
Max Alsberg committed suicide by gunshot on 11 September 1933.

Onno Klopp (9 October 1822 in Leer, Kingdom of Hanover – 9 August 1903 in Penzing, Austria) was a German historian, best known as the author of Der Fall des Hauses Stuart (The Fall of the House of Stuart), the fullest existing account of the later Stuarts. He is also known as one of the few German historians who denigrated Frederick the Great.

Hermann Alexander Diels (German: [diːls]; 18 May 1848 – 4 June 1922) was a German classical scholar, who was influential in the area of early Greek philosophy and is known for his standard work Die Fragmente der Vorsokratiker. Diels helped to import the term Presocratic into classical scholarship and developed the Diels–Kranz numbering system for ancient Greek Pre-Socratic texts.

Bernhard Klemens Maria Grzimek (German pronunciation: [ˈɡʒɪmɛk]; 24 April 1909 – 13 March 1987) was a German zoo director, zoologist, book author, editor, and animal conservationist in postwar West Germany.
