Early life and education

Pourtales was born on 4 March 1824 and regarded as a Swiss representative of an old family with linage in France, Prussia, and Bohemia.[2] After the death of his father, he succeeded to the title of Count and inherited a fortune that enabled his scientific pursuits.[2]

He was educated as an engineer.[2] He was regarded as an expert in mathematics, physics and zoology, and had interest in literature, poetry and history.[2]

Death

Pourtales died on 18 July 1880 from an unspecified "obscure internal disease".[2]

Career

Pourtales was a pupil of Louis Agassiz,[2] whom he accompanied in 1840 on glacial expeditions in the Alps and, in 1847, followed Agassiz to immigrate into the United States.[2] In 1848, he entered government service with the Coast Survey and became profoundly interested in the deep sea.[2] He made some of the first observations of the deep sea bottom and of globigerina.[2] In 1851 he assisted in the triangulation of the Florida Reef, and from 1854 until his resignation in 1873 had special charge of the office and field work of the tidal department of the Coast Survey.

In 1873 he became custodian of the Harvard Museum of Comparative Zoology, in which he had previously been assistant in zoology. He was later appointed Keeper of the Museum of Comparative Zoology, and worked closely with the curator Alexander Agassiz.[2] L. Agassiz attempted to get him a professorship.[3]

In 1871, Pourtalès published one of his most famous works, Deep Sea Corals based on his memoirs as the first in the United States to undertake deep-sea dredging[2] with USC&GS George S. Blake, and was an authority on marine zoology. A second memoir was published on the results of the Hassler Expedition.[2]

Pourtalès' last work was a report on the Florida Reef.

Honors and awards

The name Pourtalesia was given to a genus of sea urchins as found by the Challenger expedition.[2]

He was a member of the National Academy of Sciences and wrote various contributions to the Coast Survey reports, to Benjamin Silliman's American Journal of Science, and to the Proceedings of the American Association for the Advancement of Science.

Works

He published, under the auspices of the museum, several works, including:

  • Contributions to the Fauna of the Gulf Stream at Great Depths. University Press. 1867–1868.
  • Deep-Sea Corals. University Press: Welch, Bigelow, & Company. 1871.
  • Echini, crinoids, and corals. University Press. 1876.
  • Corals and Crinoids (1878)
  • Report on the Corals and Antipatharia (1880)
