Lucas Andrew Staehelin

Lucas Andrew Staehelin (February 10, 1939 – September 28, 2022) was a retired Swiss-American cell biologist. He was professor emeritus at the University of Colorado Boulder.

He developed cryofixation methods and pioneered their use for preserving cellular structures for electron microscope studies. Application of these methods to the analysis of plant, animal and bacterial cells brought insights into the nanoscale architecture and functional organization of membranous organelles and cytoskeletal systems. Staehelin taught undergraduate and graduate courses in cellular and molecular biology at the University of Colorado Boulder. Provided by Wikipedia
