In February 1953, scientists Francis Crick, Rosalind Franklin, James Watson, and Maurice Wilkins identified DNA’s double-helix structure, a groundbreaking discovery that laid the foundation for modern biotechnology. Join the 70th anniversary celebration by visiting our museum: we’ve got an X-ray crystallography machine like the one used to create Franklin’s “Photo 51,” an image critical to developing the famous two-stranded model. You can read about Nobel laureate Jennifer Doudna’s CRISPR gene-editing technology or listen to an oral history interview with Nadrian Seeman, the founder of the DNA nanotechnology field. We’re also spotlighting Moderna CEO StĂ©phane Bancel and Alnylam Pharmaceuticals CEO John Maraganore, who will both receive the Institute’s 2023 Biotechnology Heritage Award. And don’t miss our next virtual JPS talk featuring NovaXS Biotech founder Alina Rui Su and Harvard Medical School professor Daniel Kohane, who will discuss alternative methods of drug delivery.
All events are free and take place online or at the Science History Institute at 315 Chestnut Street in Philadelphia unless otherwise noted.

Subhadra Das, former curator of the Galton Collection at University College London, will discuss the colonial and racist ideas that framed the work of Francis Galton, a Victorian scientist who coined the term eugenics in 1883. This virtual Lunchtime Lecture is supported by the National Endowment for the Humanities as part of the Institute’s Innate: How Science Invented the Myth of Race project.

Our next virtual Science on Tap features American Philosophical Society fellow Patrick Walsh, who will document the birth of the endocrinology field. This talk comes with a content warning: Walsh weaves a story of grisly and ghastly experiments performed by American doctors, who made foul-smelling and foul-tasting medicine from the offcuts of recently slaughtered animals.

Join us for a panel discussion featuring NPR’s Neela Banerjee and Yale University’s Paul Sabin. Maastricht University history professor and author Cyrus Mody will moderate this talk focused on the similarities, differences, and potential conflicts between journalistic and academic accounts of the past. 
This Distillations podcast and magazine project explores the historical roots and persistent legacies of racism in American science and medicine. Innate is centered around a series of 10 weekly podcast episodes examining the scientific origins of support for racist theories, practices, and policies.

The discovery of the double-helix structure of DNA in 1953 was made possible by British chemist Rosalind Franklin (1920–1958), whose X-ray crystallography images allowed researchers Francis Crick (1916–2004) and James Watson (b. 1928) to create their famous two-strand, helical model. Shared without her knowledge by her King’s College London colleague Maurice Wilkins (1916–2004), Franklin’s “Photo 51” helped form the foundation of modern biotechnology and revolutionized the field of genetics. In 1962, four years after her untimely death at the age of 37, Crick, Watson, and Wilkins won the Nobel Prize in Physiology or Medicine for this groundbreaking discovery, while Franklin’s contribution went largely unacknowledged for many years.
