Author Draw Harvell will give a presentation on her book, “A Sea of Glass,” from 7–8:30 p.m. on Tuesday, March 14, at the Emmanuel Episcopal Parish Hall.

Anyone who has ever stood before the work of 19th-century father-son glassmaking duo Leopold and Rudolf Blaschka will understand how their exquisite pieces inspire obsessions that can span years. The Blaschkas lived in landlocked Dresden, Germany, but produced more than 800 marine invertebrate models (and also an extensive collection of plants and flowers, which is the strength of the Harvard collection), whose fidelity to their real-life counterparts is stunning. Harvell wanted to determine how many of the species depicted in the Blaschkas’ glass could still be found in the world’s oceans today, more than 150 years later.

Harvell, a professor of ecology and evolutionary biology at Ithaca, New York’s Cornell University, which is the other US institution with a large collection of Blaschka glass (she is curator of this collection), was inspired to travel around the world to pristine and degraded dive sites in a quest to find specimens that would serve as “living matches” to the Blaschka models.

Her presentation will be about her book and will feature a slide show sharing behind-the-scenes stories in the making of the film, “Fragile Legacy.”

Harvell’s book, “A Sea of Glass,” is available for purchase at Darvill’s bookstore prior to the talk. She will be happy to sign your copy after the lecture.
