Johann Karl Ludwig Martin
Johann Karl Ludwig Martin (24 November 1851, Jever (Ostfriesland) – 14 November 1942, Leiden) was a German geologist. He was professor in geology at Leiden University from 1877 to 1922. From 1880 to 1922 he also was director of the Geological Museum of Leiden. As a scientist he is known for his paleontological and stratigraphical research on the Cenozoic fauna of the Dutch East Indies, especially on mollusks. Karl Martin was student at Göttingen, where he became PhD in 1874. He then worked as a teacher at Wismar, where he studied the glacial deposits of Northern Europe. He visited the Museum of Natural History at Leiden to see the collection of Winand Staring, thus meeting the zoologist Hermann Schlegel, the director of the museum. When a chair in geology was created at Leiden University in 1877, Schlegel remembered Martin as a good candidate. As a professor at Leiden, Martins' research was on the collections of the (in 1880 newly created) Geological Museum, especi ...

Professorial Chair
Academic ranks in the United Kingdom are the titles, relative seniority and responsibility of employees in universities. In general the country has three academic career pathways: one focused on research, one on teaching, and one that combines the two. Professors In the United Kingdom, like most Commonwealth countries (excluding Australia and Canada), as well as in Ireland, traditionally a professor held either an established chair or a personal chair. An established chair is established by the university to meet its needs for academic leadership and standing in a particular area or discipline and the post is filled from a shortlist of applicants; only a suitably qualified person will be appointed. A personal chair is awarded specifically to an individual in recognition of their high levels of achievements and standing in their particular area or discipline. In most universities, professorships are reserved for only the most senior academic staff, and other academics are genera ...

1942 Deaths
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Philip Henry Kuenen
Philip Henry Kuenen (22 July 1902, in Dundee – 17 December 1976, in Leiden) was a Dutch geologist. Kuenen spent his earliest youth in Scotland, as his father (Johannes Petrus Kuenen) was professor of physics at University College, Dundee until 1906. He studied geology at Leiden University, where he was a pupil of K. Martin and B.G. Escher. He finished his studies in 1925 and then became assistant to Escher. He worked on paleontology and experimental geology. In 1929-1930 Kuenen participated in the Snellius expedition to the seas surrounding the Sunda Islands of the Dutch East Indies. In 1934 he became lecturer at Groningen University. Because the Dutch government had decided that geology would not be a major subject at Groningen University Kuenen was able to dedicate most of his time to research. Only in 1946 he became a full professor, during the German occupation in World War II the nazis had prevented this because he had British ancestors. The same year he became member o ...

Berend George Escher
Berend George Escher (4 April 1885 – 11 October 1967) was a Dutch geologist. Escher had a broad interest, but his research was mainly on crystallography, mineralogy and volcanology. He was a pioneer in experimental geology. He was a half-brother of the artist Maurits Cornelis Escher, M.C. Escher, and had some influence on his work due to his knowledge of crystallography. M.C. Escher created a woodcut ''ex libris'' for his brother 'Beer' with a stylized image of a volcano around 1922 (Bool number 91). Escher was the son of the civil engineer George Arnold Escher, G. A. Escher, a director of the Dutch watermanagement (''Rijkswaterstaat'') and his first wife, Charlotte Marie Hartitzsch. Escher spent his youth in Switzerland. He studied geology at the ETH Zurich, Eidgenössische Technische Hochschule (Technical University) of Zürich, where he was a pupil of Albert Heim.

Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied.
