Jeremy David Pickett-Heaps 1940–2021

Jeremy Pickett-Heaps was a biologist whose acute observational powers were fed by a deep fascination for how cells work; he had an affinity for the myriad diversity of algae and other protists in general and for what they could teach us about all cells. An early adopter of the electron microscope, he made fundamental discoveries in plant cell division and green algal phylogeny that developed into studies on cell division in general: first with the highly-ordered diatoms and other protists, and later with animal cells. In the latter part of his career, Jeremy mastered time-lapse micro-cinematography to document the dynamic lives of cells and, through the resultant movies and his enthusiastic teaching, introduced many to the wonders of microscopic life.
