Mary-Dell Chilton (born February 2, 1939, died June 24, 2026) was an amazing American scientist. She was a biochemist, which means she studied the chemistry of living things. Mary-Dell was also an inventor and a writer. She helped create modern plant biotechnology, which is a way to improve plants using science.
She worked at Washington University in St. Louis and later at Syngenta Biotechnology, Inc. Mary-Dell Chilton became famous in 1977 for a big discovery. She found out how a special type of bacteria, called Agrobacterium, could transfer its DNA into plant cells. This was a huge step in understanding how to change plants.
During her life, she received many important awards. These included the World Food Prize in 2013 and the National Medal of Technology and Innovation from President Joe Biden in 2023. She was also honored in the National Inventors Hall of Fame.

Growing Up and Going to School
Mary-Dell Chilton was born in Indianapolis, Indiana, on February 2, 1939. She spent her childhood in Southern Pines, North Carolina, where her grandmother raised her.
She went to a private school when she was young. Later, she studied chemistry at the University of Illinois Urbana-Champaign. There, she earned two degrees: a Bachelor of Science and a Ph.D. After that, she continued her advanced studies at the University of Washington in Seattle.
Amazing Discoveries in Plant Science
Mary-Dell Chilton taught and did research at Washington University in St. Louis. In the late 1970s and early 1980s, she led a team that made a huge breakthrough. They created the very first transgenic plants. These are plants that have had a small piece of DNA from another organism added to them.
Her work led to the first genetically modified plants. These special plants could resist pests or survive better without much water. This was a big step for farming!
How Mary-Dell Chilton Helped Plants
In 1977, Mary-Dell made a key discovery. She showed that a tiny piece of DNA from a bacterium called Agrobacterium could move into plant cells. This bacterium usually causes a plant disease called crown gall.
Mary-Dell's team found a way to "disarm" the Agrobacterium. This meant they removed the parts of the bacteria's DNA that caused disease. But they kept the part that could transfer DNA into plants. This was like taking away the bad parts of a tool but keeping the useful parts.
In 1983, she and her team used this "disarmed" Agrobacterium to create the first genetically modified plants. Because of her pioneering work, people sometimes called her the "queen of Agrobacterium."
Working in the Private Sector
After her big discoveries, Mary-Dell Chilton started working in the private industry. She joined Syngenta Biotechnology in Research Triangle Park. There, she became a vice president and a lead scientist.
She wrote over 100 scientific papers, sharing her knowledge with the world. She was known as a Distinguished Science Fellow at Syngenta. She also worked for CIBA-Geigy Corporation, which later became part of Syngenta.
Life Outside of Science
Mary-Dell Chilton loved canoeing. Even at 76 years old, she enjoyed a trip through Stillwater Canyon in Utah. She had two sons, Mark and Andrew.
Mary-Dell Chilton passed away on June 24, 2026, at her home in Carrboro, North Carolina. She was 87 years old.
Awards and Special Honors
Mary-Dell Chilton received many awards for her important work. She earned an honorary doctorate from the University of Louvaine. She also received the John Scott Medal and the Benjamin Franklin Medal in Life Sciences. She became a member of the United States National Academy of Sciences.
In 2011, the Crop Science Society of America gave her their Presidential Award. To celebrate her achievements, Syngenta created the Mary-Dell Chilton Center in 2002. This is a special building at their facility in Research Triangle Park, North Carolina.
In 2013, she was given the prestigious World Food Prize. This award recognizes people who improve the world's food supply. In 2015, she was chosen for the National Inventors Hall of Fame. In 2020, she was featured in a special display at the Smithsonian National Museum of American History. She was also recognized as a Pioneer Member of the American Society of Plant Biologists.
In 2023, President Joe Biden presented her with the National Medal of Technology and Innovation. This is one of the highest honors for technological achievement in the United States.
