The glass sea creatures (alternately called the Blaschka sea creatures, glass marine invertebrates, Blaschka invertebrate models, and Blaschka glass invertebrates) are works of glass artists Leopold and Rudolf Blaschka. The artistic predecessors of the Glass Flowers, the sea creatures were the output of the Blaschkas' successful mail-order business of supplying museums and private collectors around the world with sets of glass models of marine invertebrates.
Between 1863 and 1880, the Blaschkas – working in Dresden – executed at least 10,000 of these highly detailed glass models, representing some 700 different species.Crystal Sarakas, Corning exhibit shows sea creatures in glass, Democrat & Chronicle (August 6, 2016).
A number of large collections of the models are held by museums and other academic institutions. Harvard's Museum of Natural History exhibits many of the Blaschka's glass creations, and its Museum of Comparative Zoology hold 430 items in the Blaschka Glass Invertebrate Collection and display about 60 at any given time.Blaschka Glass Invertebrate Collection, Museum of Comparative Zoology, Harvard University (2016), Cornell University has about 570 items in its collection and has restored some 170 of these,Out of the Teeming Sea: The Cornell Collection of Blaschka Invertebrate Models, Albert R.

Inspiration
In 1853, shortly after the death of his father and wife Caroline, the latter to a cholera epidemic, Leopold Blaschka – grief stricken and in need of a vacation – traveled to the United States. En route the ship was becalmed and lay still upon the sea for two weeks. During this period of forced idleness, Leopold studied and sketched the local marine invertebrate population, intrigued by the transparency of their bodies similar to the glass his family had long worked. Short title: "Blaschka – English version". Translation by Peter Silbernagl. Lead sentence: "In September 2000, an association was founded in Dresden-Hosterwitz with the aim to establish a museum-type memorial for the work of Leopold and Rudolf Blaschka and to treasure the memory of those two glass-artists." Earliest English-language title: The Association "Naturwissenschaftliche Glaskunst – Blaschka-Haus e.V.". Johanna Dühning, Chairman of the Association; translation by Benjamin Pentzold ().
Leopold felt a sense of quiet, inspirational, wonder at these luminescent ocean dwellers, a sense which he recorded and translated by Henri Reiling: "It is a beautiful night in May. Hopeful, we look out over the darkness of the sea, which is as smooth as a mirror; there emerges all around in various places a flashlike bundle of light beams, as if it is surrounded by thousands of sparks, that form true bundles of fire and of other bright lighting spots, and the seemingly mirrored stars. There emerges close before us a small spot in a sharp greenish light, which becomes ever larger and larger and finally becomes a bright shining sunlike figure."
This sense of wonder would fuel his later work but, in the meantime and upon his return to Dresden, Leopold focused on his family business which was the production of the glass eyes, costume ornaments, lab equipment, and other such fancy goods and specialty items;Harvard University Herbaria and Botany Libraries plus the task of training of his son and apprentice (who was his eventual successor), Rudolf Blaschka.
Reichenbach's request
Director of the natural history museum in Dresden, Prof. Reichenbach was faced with an annoying yet seemingly unsolvable problem in regards to showing marine life. Land-based flora and fauna was not an issue, for it was a relatively simple matter to exhibit mounted and stuffed creatures such as gorillas and elephants, their lifelike poses attracting and exciting the museum's visitors. Invertebrates, however, by their very nature, posed a problem."Leopold + Rudolf Blaschka {...} The Glass Aquarium {...}". Design Museum (designmuseum.org). Retrieved 2015-06-10. In the 19th century the only practiced method of showcasing them was to take a live specimen and place it in a sealed jar of alcohol. This of course killed it but, more importantly, time and their lack of hard parts eventually rendered them into little more than colorless floating blobs of jelly. Neither pretty nor a terribly effective teaching tool, Prof. Reichenbach wanted something more, specifically 3D colored models of marine invertebrates that were both lifelike and able to stand the test of time. By coincidence, in 1863, he "saw an exhibition of highly detailed, realistic glass flowers created by a Bohemian lampworker named Leopold Blaschka."
Enchanted by the botanical models, and positive that Leopold held the key to ending his own showcasing issue, in 1863 Reichenbach convinced and commissioned Leopold to produce twelve model sea anemones.Museum of Natural History Berlin, Historical collection of pictures and writings – Katalog über Blaschka's Modelle, L. Blaschka, Dresden, 1885 These marine models, hailed as "an artistic marvel in the field of science and a scientific marvel in the field of art", were a great improvement on previous methods of presenting such creatures: drawings, pressing, photographs and papier-mâché or wax models.Goodyear, Anne Collins, and Weitekamp, Margaret A. Analyzing Art and Aesthetics. Artefacts: Studies in the History of Science and Technology; v. 9. 2013. and exactly what Prof. Reichenbach needed. Moreover they, at last, provided an outlet for the wonder Leopold had felt all those years ago when observing the phosphorescent ocean life.
The key fact, though, was that these glass marine models were, as would soon be acknowledged, "perfectly true to nature", and as such represented an opportunity both for the scientific community and the Blaschkas themselves (to create sea anemone images faithful to nature, images from P.H. Gosse's Actinologia Britannica, 1860, were utilised).Wertheimer, Douglas (2024), Philip Henry Gosse: A Biography, Glasgow: Brethren Archivists and Historians Network, pp.351. All but two of the 68 glass models in the first Blaschka sale catalog of 1870 were based on Gosse's book. Knowing this, and thrilled with his newly acquired set of glass sea creatures, Reichenbach advised Leopold to drop his current and generations long family business of glass fancy goods and the like in favor of selling glass marine invertebrates to museums, aquaria, universities, and private collectors. Advice which would prove wise and fateful both economically and scientifically, for Leopold did as the Dresden natural history museum director suggested.
A successful business
Unlike the Glass Flower, which began as a private commission to a single University's museum, the Blaschka glass sea creatures were a global enterprise. They reflected a change in attitude: "as popular interest in the history and sciences of the natural world burgeoned during the latter half of the 19th century, the sea became particularly alluring. The spread of home aquariums and the advent of deep-sea diving revealed a new frontier, filled with wondrous and unusual creatures." During this time of interest in the natural world, it became a sign of culture and sophistication to exhibit examples of life in one's drawing rooms and parlors. The Blaschkas, aware of public and museum demand, created a mail-order business. They sold 10,000 glass invertebrates globally. It is said that "the world had never seen anything quite like the beautiful, scientifically accurate Blaschka models." Yet they were available via mail-order, through a local card catalog. Ward's Natural Science sold a small glass octopus for approximately $2.50. Museums and universities displayed them much as Prof. Reichenbach had because natural history museums had a problem showcasing marine invertebrates. The mail-order enterprise succeeded for two reasons: 1- there was substantial global demand; 2- they were the glass artists most capable of crafting accurate models. Initially the designs for these were based on drawings in books, but Leopold was soon able to use his earlier drawings to produce highly detailed models of other species, and his reputation quickly spread.
As Leopold wrote in an English-language trade catalog preserved at the Rakow Research Library at The Corning Museum of Glass: "[Models of invertebrate animals] have been purchased by... museums and scholastic establishments in all the quarters of the globe... in New Zealand... in Tokio [sic], Japan... for the Indian Museum in Calcutta... in the United States of America by Professor Ward's Natural Science Establishment in Rochester, New York; for the Museum of Comparative Zoology in Cambridge, Massachusetts; for the Boston Society of Natural History; the University of Cornell; the Wellesley Female College... In Great Britain, Scotland and Ireland, copies have been conveyed to London, Edinburgh and Dublin... In Austria, orders have not only been made for the Imperial Royal Court collection, but also for the universities in Innsbruck, Graz, Czernovitz, and so forth. In Germany, purchases have been made for the universities of Berlin, Bonn, Koenigsberg, Jena, Leipzig, Rostock and many other museums."
Leopold gradually extended his range of work by studying marine animals from the North Sea, Baltic Sea and Mediterranean, and later constructed an aquarium at his house, in order to keep live specimens from which to model.
Yet the fate of the marine invertebrate mail-order business was ultimately to be tied to those bought by Harvard's Museum of Comparative Zoology. At some time after the museum's founding in 1859, a collection of 430 glass sea creatures were purchased by either Louis Agassiz, the first director, or his son and successor Alexander Agassiz. and was likely at least partially unpacked by Alexander Agassiz's personal secretary Elizabeth Hodges Clark, one of the first and few women with any authority in the museum.Harvard University Herbaria and Botany Libraries - https://hmsc.harvard.edu/online-exhibits/women-museum/finding-work This set was not the largest ever sold and the models were no different from any of the others made by the Blaschkas, but their effect was to be greater than all the rest combined.
