Caesar Rudolf Boettger
Caesar Rudolf Boettger (20 May 1888 – 8 September 1976) was a German zoologist born in Frankfurt am Main. He specialized in malacology, particularly studying the land snails and slugs. In 1912 he obtained his PhD from the University of Bonn, and in 1914 embarked on a scientific expedition to Africa and the Orient. During World War I, he was stationed in France and Turkey. In 1932 he became a private lecturer at the University of Berlin, where in 1938 he was appointed professor of zoology. In 1947 he became a professor of zoology at Braunschweig University of Technology, where he established a museum of natural history. After retirement in 1956, he undertook five research trips to North America (including Mexico and Hawaii). In 1965 he was visiting curator at the University of Michigan and in 1967/68 took part in a research project of the Naval Medical Field Research Laboratory in North Carolina. Boettger has over a dozen species named after him, as well as a gastropod genus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dueling Scar
Dueling scars (german: link=no, Schmisse) have been seen as a "badge of honour" since as early as 1825. Known variously as " scars", "the bragging scar", "smite", "" or "", dueling scars were popular amongst upper-class Austrians and Germans involved in academic fencing at the start of the 20th century. Being a practice amongst University students, it was seen as a mark of their class and honour, due to the status of dueling societies at German and Austrian universities at the time.DeMello, Margo (2007). ''Encyclopedia of body adornment'' Greenwood Publishing Groupp. 237 . The practice of dueling and the associated scars was also present to some extent in the German military. Foreign tourists visiting Germany in the late 19th century were shocked to see the students, generally with their , at major German universities such as Heidelberg, Bonn, or Jena with facial scars – some older, some more recent, and some still wrapped in bandages. The sport of academic fencing at the time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Academic Staff Of The Humboldt University Of Berlin
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientists From Frankfurt
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

Mollusks
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Senckenberg
The Naturmuseum Senckenberg is a museum of natural history, located in Frankfurt am Main. It is the second-largest of its type in Germany. The museum contains a large and diverse collection of birds with 90,000 bird skins, 5,050 egg sets, 17,000 skeletons, and 3,375 spirit specimens (a specimen preserved in fluid). In 2010, almost 517,000 people visited the museum. The building housing the Senckenberg Museum was erected between 1904 and 1907 outside of the center of Frankfurt in the same area as the Johann Wolfgang Goethe University, which was founded in 1914. The museum is owned and operated by the Senckenberg Nature Research Society, which began with an endowment by Johann Christian Senckenberg. Attractions include a '' Diplodocus'' (donated by the American Museum of Natural History on the occasion of the present museum building's inauguration in 1907), the crested Hadrosaur ''Parasaurolophus'', a fossilized '' Psittacosaurus'' with clear bristles around its tail and vis ...

Kei Islands
The Kai Islands (also Kei Islands) of Indonesia are a group of islands in the southeastern part of the Maluku Islands, located in the province of Maluku. The Moluccas have been known as the Spice Islands due to regionally specific plants such as nutmeg, mace, and cloves that originally intrigued the European nations of the 16th century. Though originally Melanesian, many islanders were exterminated in the 17th century during the spice wars, particularly in the Banda Islands. A second influx of Austronesian immigrants began in the early 20th century under the Dutch and continued in the Indonesian era. Administrative divisions The Kai Islands consist of the two distinct second-tier administrations, both in Maluku Province. The Southeast Maluku Regency (Maluku Tenggara) is sub-divided into eleven administrative districts (''kecamatan''). Though it is geographically in the Kai Islands, the city of Tual forms a separate regency-level administration and is not part of the Sout ...

Land Snail
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial gastropod mollusks that have shells (those without shells are known as slugs). However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water. Land snails are a polyphyletic group comprising at least ten independent evolutionary transitions to terrestrial life (the last common ancestor of all gastropods was marine). The majority of land snails are pulmonates that have a lung and breathe air. Most of the non-pulmonate land snails belong to lineages in the Caenogastropoda, and tend to have a gill and an operculum. The largest clade of land snails is the Cyclophoroidea, with more than 7,000 species. Many of these operculate land snails live in habitats or microhabitats ...
