Nathanael Sendel
Nathanael Sendel (August 1686 – 1757) was a German physician and naturalist who was among the first to examine the paleontological aspects of Baltic amber. His major work was “Historia Succinorum” (1742) which described a large collection of Baltic amber and its inclusions.
Sendel was born in Elbing (Elbląg) and after attending the local gymnasium (1691) where his father Samuel was a teacher, he went to Danzig and then to the University of Wittenberg (1709) and completed medical studies at the University of Halle (1712). He published "Thesium ex Synopsi cum anti-thesibus pugillus" in 1708 and in 1709 “Dissertatio medico-physica de sapore”. His doctoral thesis under Georg Ernst Stahl (1659-1734) was titled “De Causis Praecipuis, Effectuum Tragicorum in Medicina”. He returned to practice privately in Elbing and became a city physician from 1716. He collected amber and began to interact with scientific societies. He collaborated with Johann Philipp Breyne (1680-1764) who had a great network across Europe and England. Jacob Theodor Klein (1685-1759) from Danzig was another collaborator. His work on amber was titled "Electrologiae per varia tentamina historica ac physica continuandae" (1725-1728) which examines the origin of amber and its properties. He also examined the animal inclusions and began to examine collections including those of others. From the 1720s Sendel was associated with the Dresden amber cabinet which included donations by the Prussian King Friedrich Wilhelm I and he was involved in sorting and cataloguing the collection. Sendel believed that amber was formed in cracks deep in the earth and rejected the theory that amber came from tree resin. He suggested that insects that crawled into the cracks and crevices of the earth got embedded in the liquid state of the amber. It was in 1757 that Mikhail Vasilyevich Lomonosov (1711–1765) determined that amber was fossil resin. Sendel was elected to the Leopoldina academy in 1743.[1]
Sendel's major work was the folio volume Historia Succinorum with 13 copperplate engravings by C. F. Boetius (1706-1782) describing 250 amber inclusions, mostly arthropods.[2] He described many fossil "butterflies", which were mostly caddisflies.[3]
