Dorothea Zucker-Franklin (August 9, 1929 – November 24, 2015) was a physician and medical researcher in the fields of hematology, immunology and cell biology.

Following her internship and residency, she trained in electron microscopy, and would become well-known for her use of this technique to study blood cells.

In 1943, during the German occupation of the Netherlands, Zucker-Franklin was captured and interned in a camp; after their release, the family spent the next few years in hiding.

Through this technique she worked to elucidate the mechanisms of phagocytosis and the structure and function of white blood cells, platelets and megakaryocytes.

[6] That year she published the first edition of Atlas of Blood Cells: Function and Pathology in collaboration with Carlo Grossi;[2] the textbook, extensively illustrated with electron micrographs, has been called "the finest in its class".

[8] She was awarded an honorary PhD by the City University of New York in 1996[3] and was made a fellow of the American Academy of Arts and Sciences in 2001.
