Katharine Foot

Katharine Foot (October 14, 1852 – 1944) was an American zoologist and cytologist who conducted research with her laboratory partner, Ella Church Strobell. They were known for their advances in developing new techniques for making microscope samples and for taking micrographs of cells.

Biography Foot was born in Geneva, New York in 1852. The first edition of American Men of Science described her being educated through private schools while growing up.

Foot lived in London for a period in the 1930s, but moved to the United States by the time of the Second World War. She died in 1944, and her last address showed her residing in Camden, South Carolina.

In 1892, after her first six weeks in a course on invertebrates in Woods Hole, Charles Ottis Whitman delegated Foot to work on the maturation and fertilization of the egg of the earthworm, Allolobophora foetida. She wrote a paper on the subject that appeared in the Journal of Morphology in 1894. In 1896, she became the first woman to give a lecture at the Woods Hole Laboratory. Her lecture was titled "The centrosomes of the fertilized egg of Allolobophora foetida".

Ella Strobell began working as Foot's assistant in 1897. In 1899, Strobell's name began coauthoring papers with Foot. Foot and Strobell were among the first to photograph the development stages of fertilized eggs and together researched the role of chromosomes in hereditary, sex-linked characteristics. Additionally, they developed a technique for creating samples at low temperatures for viewing under the microscope.

Between 1906 and 1913, Foot and Strobell researched certain stages of chromosomal development of squash bugs. This was believed to be done in a Laboratory of their own in New York City. Foot and Strobell participated in debates on the role of chromosomes in transmitting definite units of hereditary information such as sex-linked characteristics. They defended their position against T.H. Morgan. In 1914, Foot and Strobell traveled to England to continue their research under Harry Eltringham of New College Oxford. Their research stopped in 1917 when Strobell became ill.

By the end of the First World War, Foot went on to volunteer for the American Red Cross in Paris. She researched the life cycle of the louse, Pediculus vestimenti, to develop a method of control.
