Laurence “Larry” Kedes, Molecular Geneticist, Dies at 83

In addition to isolating the first protein-coding gene from a eukaryote, Kedes furthered scientists’ understanding of actin genes and also laid the foundations for modern DNA databases such as GenBank.

Laurence “Larry” Kedes, a molecular geneticist and biological chemist, died January 6 at age 83 following a period of declining health. Kedes’s work often placed him at the forefront of emerging technologies, from DNA sequencing to bioinformatics, and he capitalized on such tools to further scientists’ understanding of how genes are regulated.

“Larry excelled at finding interesting problems, asking the right questions, and then working with the best people to answer them,” says Pragna Patel, a human geneticist at the University of Southern California (USC) who was first recruited to the university by Kedes. “He was a man who was ahead of his time in terms of thinking about biological problems.”

Born in 1937, Kedes attended Wesleyan University for three years before transferring to Stanford University’s School of Medicine for his bachelor’s and medical degrees. After graduating in 1962, Kedes completed postdoctoral research at the National Cancer Institute and MIT ...

    Amanda first began dabbling in scicom as a master’s student studying marine science at Moss Landing Marine Labs, where she edited the student blog and interned at a local NPR station. She enjoyed that process of demystifying science so much that after receiving her degree in 2019, she went straight into a second master’s program in science communication at the University of California, Santa Cruz. Formerly an intern at The Scientist, Amanda joined the team as a staff reporter and editor in 2021 and oversaw the publication’s internship program, assigned and edited the Foundations, Scientist to Watch, and Short Lit columns, and contributed original reporting across the publication. Amanda’s stories often focus on issues of equity and representation in academia, and she brings this same commitment to DEI to the Science Writers Association of the Rocky Mountains and to the board of the National Association of Science Writers, which she has served on since 2022. She is currently based in the outdoor playground that is Moab, Utah. Read more of her work at www.amandaheidt.com.
