Lydia Maria Adams DeWitt facts for kids

Lydia Maria Adams DeWitt (born Lydia Maria Adams on February 1, 1859 – died March 10, 1928) was an important American scientist. She was a pathologist and an anatomist. This means she studied diseases and the structure of living things.

Early Life and Education

Lydia Maria Adams was born in Flint, Michigan. She was the second of three children. Her father was a lawyer. When Lydia was five, her mother passed away. Her mother's sister then helped raise Lydia and her siblings.

Lydia went to public schools in Flint. She became a teacher. Later, she studied at the Michigan State Normal School. In 1878, she married Alton D. DeWitt, who was also a teacher. They had two children, Stella and Clyde. The family moved often because Alton took different teaching jobs. Lydia also taught in various public schools.

Career and Research Discoveries

In 1895, Lydia DeWitt started studying medicine at the University of Michigan. She earned her Doctor of Medicine degree in 1898. The next year, she received a Bachelor of Science degree. During this time, Lydia and Alton DeWitt separated.

Lydia DeWitt stayed at the University of Michigan to begin her research career. She worked as an anatomy demonstrator from 1896 to 1897. Then, she became an assistant professor of histology (the study of tissues) until 1902. From 1902 to 1910, she was an associate professor of histology. In 1906, she took a short break to study at the University of Berlin in Germany.

That same year, she was recognized in the first edition of American Men of Science. This was for her important work in microscopic anatomy and neuroanatomy (the study of the nervous system).

In 1910, DeWitt moved to Washington University in St. Louis. She became an instructor of pathology there. She also worked for the St. Louis Department of Health as a pathologist and bacteriologist. Her research was so good that she was invited to join the University of Chicago. She started working there in 1912 to research treatments for tuberculosis. She was an assistant professor of pathology until 1918. Then, she became an associate professor. She retired in 1926.

Women in Science

As a woman scientist, Lydia DeWitt faced challenges. She was not allowed to join the Faculty Research Club at the University of Michigan. So, in 1902, she started her own group called the Women's Research Club. She was its first leader.

Key Research Areas

DeWitt's research covered many different topics. She studied the pathology of tuberculosis. She also looked closely at muscles, how they connect to nerves, and a disease called myositis ossificans.

Her early research at the University of Michigan focused on nerve endings in different types of muscles. She published studies on muscle spindles in 1897. Her first solo research in 1901 was about pyloric glands in different animals.

While at the St. Louis Department of Health, she researched diphtheria and how to diagnose typhoid fever. She also worked on isolating islets of Langerhans cells from the pancreas. She found that these cells produced a substance important for how the body uses sugar. This work helped set the stage for the discovery of insulin and its role in diabetes.

At the University of Chicago, DeWitt and her team tried to develop a drug to treat tuberculosis. They worked with other scientists like Hope Sherman and Gladys Leavell. They studied different dyes, such as methylene blue and trypan red, as possible ingredients for a new medicine. While their specific drug didn't work right away, their methods helped future scientists develop successful treatments for tuberculosis.

Honors and Recognition

Lydia DeWitt received many honors for her work. In 1902, she joined the Association of American Anatomists. The University of Michigan gave her an honorary Master's degree in 1914.

She was the president of the Chicago Pathological Society from 1924 to 1925. The American Medical Association made her an associate fellow. She was also a member of the Michigan Medical Society and the American Association of Pathologists and Bacteriologists.

Later Life and Legacy

Lydia DeWitt passed away at age 69 in Winters, Texas. She was at her daughter's home. She had been dealing with long-term health issues. Today, a research grant at the University of Michigan helps support women scientists. It is named in her honor.
