Karl Ernst von Baer (1792-1876) Kimberly A. Buettner Best known for his contributions to the field of embryology, Karl Ernst von Baer also pursued a variety of other areas of study including medicine, botany, zoology, and anthropology. Committing his life to scientific research, von Baer's work led to the advancement of the understanding of mammalian reproduction, development, and organ functioning. His embryological discoveries ultimately led him to a view of development that supported epigenesis and refuted long-held thinking about preformation. 2007-10-31 4 Jul 2018 - 4:40:59am
Benjamin Harrison Willier (1890-1972) Karen Wellner Benjamin Harrison Willier is considered one of the most versatile embryologists to have ever practiced in the US. His research spanned most of the twentieth century, a time when the field of embryology evolved from being a purely descriptive pursuit to one of experimental research, to that of incorporating molecular biology into the research lab. Willier was born on 2 November 1890 near Weston, Ohio to Mary Alice Ricard. He spent his childhood doing farming chores and running the farm while his father, David Willier worked as a banker. 2010-06-28 4 Jul 2018 - 4:40:59am
Ernest John Christopher Polge (1926-2006) Renee Bailey Twentieth-century researcher Ernest John Christopher Polge studied the reproductive processes of livestock and determined a method to successfully freeze, thaw, and utilize viable sperm cells to produce offspring in animals. In 1949, Polge identified glycerol as a cryoprotectant, or a medium that enables cells to freeze without damaging their cellular components or functions. Several years later, Polge used glycerol in a freezing process called vitrification, which enabled him to freeze poultry sperm, thaw that sperm, and use it to fertilize vertebrate embryos. 2018-01-30 4 Jul 2018 - 4:40:59am
Regnier de Graaf (1641-1673) Ellen M. Dupont Regnier de Graaf, a Dutch physician and anatomist, was born 30 July 1641 in Schoonhoven, the Netherlands.

Victor Jollos (1887-1941) B. R. Erick Peirson Victor Jollos studied fruit flies and microorganisms in Europe and the US, and he introduced the concept of Dauermodifikationen in the early 1900s. The concept of Dauermodifikationen refers to environmentally-induced traits that are heritable for only a limited number of generations. Some scientists interpreted the results of Jollos's work on Paramecium and Drosophila as evidence for cytoplasmic inheritance. Jollos was forced to emigrate from Germany to the United States due to anti-semitic government policies in 2014-09-16 4 Jul 2018 - 4:40:59am
The Marine Biological Laboratory, Woods Hole, Mass. 1935 B.R. Coonfield By the 1930s, the MBL had become "the" place to go during the summer for biological research and training. Luminaries such as Frank Lillie, Edmund Beecher Wilson, Edwin Grant Conklin, and Thomas Hunt Morgan took their students, packed up their families and research labs, and headed to the MBL. They worked in labs, ate together in the Mess, and they often lived in the limited on-campus housing. Life at the MBL was a life where fun, family, and science intertwined. This film, taken in 1935 by B. R. Coonfield of Brooklyn College, captures snippets of life at the MBL. 1935 4 Jul 2018 - 4:40:59am
