Dr. Leasure K. Darbaker, a physician of Wilkinsburg, Pennsylvania, who was for many years a member of the Botanical Society of America and who died in 1952, bequeathed funds to the Society to provide an annual sum (to be known as the Darbaker Prize) for a "grant or grants in Microscopical Algae." The award or awards will be made annually by a committee of the Society; the first Committee on The Darbaker Prize in 1955 consisted of William Randolph Taylor, chairman, Harold C. Bold, John D. Dodd, Ruth Patrick, and Gilbert M. Smith. Nominations for the 1955 award were accompanied by a statement of the merits of the case and by reprints supporting the candidacy. The recipient receives a certificate and a $1,000 award.

The Botanical Society of America and the Phycological Society of America are pleased to join together in seeking nominations for the 2024 Darbaker Prize in Phycology.

2019 - Dr. Louise Lewis, University of Connecticut, Dr. Lewis' impact on the field of phycology is remarkable.  Her work spans ecology, physiology, ultrastructure, phylogenetic diversification, and organellar genomics. Dr. Lewis did some of the earliest molecular systematic research on microalgae in her graduate work at The Ohio State University, at the time using groundbreaking techniques in the nascent field of gene sequencing and analysis. Dr. Lewis has maintained a steady and prolific output of high-impact publications throughout her career, including a 2004 paper in the American Journal of Botany that as recently as last year was the most-read paper in the journal, more than a decade after its appearance.

No awards given 2013-2018

2012 - Dr. Walter Adey, National Museum of Natural History, Smithsonian Institution. Dr. Adey has been a pioneer of modern phycology. His development of modern coralline taxonomy and the structural analysis have provided the underpinnings for our present understanding of this group that is now being enhanced by molecular methods. He has further pioneered the system of using filamentous algae as scrubbers toward clean water production and biofuels generation.

Dr. Sabeeha Merchant, University of California at Los Angeles. Dr. Merchant has been instrumental in developing the genetics and genomics of Chlamydomonas as a model organism. Her work has elucidated the role of metabolic cofactors and iron and copper utilization in the biogenesis of the photosynthetic apparatus, thus providing the basic understanding of chloroplast development for green algae and plants.

2011 - Dr. Sallie (Penny) Chisholm, Massachusetts Institute of Technology. Dr. Chisholm’s recent and past publications are on the significant role of the microalgal group Prochlorococcus. She and her collaborators have elucidated their wide distribution in the oceanic environment, and have demonstrated essential critical environmental factors, including light and nutrients which account for the varied distribution and certain ecotypes and species. Their most recent emphasis is on the genomic characterization with respect to phosphate uptake, and the potential involvement of the cyanophages in the transfer of genetic material. She has also offered her well considered opinion in influential scientific journals to discourage oceanic Fe fertilization since it likely will seriously impact the ecosystem.

2010 - Dr. Brian Palenik, Scripps Institution of Oceanography, University of California, San Diego, CA. Dr. Palenik is a leader in the field of oceanographic phytoplankton genomics. He has focused mostly on cyanobacterial organisms, but he was also first author on a seminal paper on Ostreococcus, the smallest eukaryotic phytoplankter whose genome was sequenced in its entirety. Palenik was the lead scientist in that effort, published in PNAS. In addition to his research, Dr. Palenik is active in communicating the science of genomics and oceanography to the general public. He was also instrumental in designing and implementing an exhibit in a public aquarium on DNA sequencing and genomics of marine organisms.

2009 - Dr. Patrick Keeling, Canadian Institute for Advanced Research, Evolutionary Biology Program, Department of Botany, University of British Columbia, Vancouver, BC, Canada.
