Dafna Bar-Sagi was a Senior Staff Investigator at Cold Spring Harbor Laboratory from 1984-1994. In 1986 Dr. Bar-Sagi and her postdoc advisor, Dr. James Feramisco observed that injection of oncogenic KRAS protein into fibroblasts caused morphological changes, including pronounced membrane ruffling and the accumulation of pinocytic vesicles. Recent investigations into the metabolism of cancers, especially cancers driven by mutant KRAS, have transformed macropinocytosis from a phenotypic curiosity to a key player in the nutrition of pancreatic cancer cells.
Dafna is currently a Professor in the Departments of Biochemistry & Molecular Pharmacology and Medicine, and Senior Vice President and Vice Dean for Science at New York University’s School of Medicine.

In 1924, Dorothy Bergner replaced John Belling as Albert Blakeslee's principal coworker. Prior to her time in CSH, Dorothy Bergner was the first to describe the natural occurrence of sporophytic haploids in the weed species Datura stramonium in 1922. With Bergner, Albert Blakeslee discovered a thirteenth trisomic in Datura. As there are only 12 chromosome pairs, a different explanation was sought, and found. She is the author of eight papers related to plant science and genetics. In 1937 it was discovered that colchicine will paralyze mitotic cell division and give rise to cells in which the chromosome number has been doubled. Using this technique, Blakeslee and Bergner produced polyploids, and periclinal chimeras. She worked at the C.I.W. Department of Genetics until 1942.
Martha Chase graduated from the College of Wooster in Ohio in 1950 when she was hired as a research assistant by Dr. Alfred D. Hershey, a biologist who was investigating how viruses replicate. Working at the Cold Spring Harbor Laboratory in 1952, the two devised one of the most iconic and elegant experiments in modern biochemistry to determine whether DNA or protein carried genetic information.
Ms. Chase left Cold Spring Harbor in 1953 to work at the Oak Ridge National Laboratory in Tennessee and later at the University of Rochester. She returned to Cold Spring Harbor each summer during the 1950's to participate in the meetings of the influential Phage Group of biologists. In 1959, she began work on her doctorate at the University of Southern California. After receiving it in 1964, she returned to Cleveland. She passed away in Cleveland in 2003.
Louise Chow and her husband, UAB Professor Thomas Broker, joined the Cold Spring Harbor Laboratory in 1975. Initially, her work focused on the genetic organization, RNA transcription and DNA replication of human adenoviruses, which cause common respiratory and gastrointestinal tract infections. In the course of this work, in 1977, she and her collaborators discovered the totally unexpected phenomenon of split genes and RNA splicing. This work became the foundation for the understanding the human and the other eukaryotic genomes, the origin of most of their encoded proteins and the cause of many different genetic diseases. Chow was made Senior Staff Investigator in 1977 and Senior Scientist in 1979.
She left Cold Spring Harbor and joined the University of Rochester in 1984, where her team concentrated on distinguishing the growing number of human papillomavirus genotypes as well as the spliced structures of their mRNAs. Louise is currently a professor of Biochemistry and Molecular Genetics at the University of Alabama at Birmingham and a foreign associate with the National Academy of Sciences.

Paula De Lucia came to Cold Spring Harbor in 1964 under the guidance of Dr. John Cairns. In 1969 Paula DeLucia and John Cairns discover that the 5 to 3 polymerase I activity of DNA polymerase I in E. coli is not required for DNA replication.
Because of Paula DeLucia and John Cairns, the main player in DNA replication was determined to be DNA Polymerase III, not polymerase I. One of the main functions of DNA Polymerase I is to repair damaged DNA. This mutation hindered the enzymatic ability to complete this task, thus reinforcing the idea that repair was one of the enzymes main purposes.
She was active at Cold Spring Harbor until 1971.

Birgit Zipser was a student in the 1975 Leech course. In 1978 she was the first appointment made to the newly organized Neurobiology area at CSH, her title was Senior Staff Investigator.
In the spring of 1979, she helped organize an Invertebrate Neurobiology Workshop in Jones, using Marie H. Robertson funds. In 1978 Zipser started collaborating with Ron McKay. She became the founding, and sole, member of the Neuroscience division, studying electrophysiology of leech ganglia. She left Cold Spring Harbor in December of 1984. Since 1984 Dr. Zipser has studied the human brain, particularly enzymes related to Alzheimer’s Disease. Dr. Zipser is currently Professor Emerita in the Department of Physiology at Michigan State University where she is working on developing a therapeutic reagent again cancer.
In 1980 Birgit Zipser persuaded Susan Hockfield, a postdoctoral fellow at UCSF to join the scientific staff at the Cold Spring Harbor Laboratory as a Senior Staff Investigator. The Neurobiology group was together until 1985. Sue Hockfield left Cold Spring Harbor in May 1985.Dr. Hockfield would join Yale in 1985 and became a dean of its graduate school and later as provost. From 2004-2012 she served at the 16th president of MIT, most notably the first female president of the institute.
Anne Lutz worked at the Carnegie Institution of Washington Station for Experimental Evolution from 1905-1910. While George Shull was shuttling between California and Cold Spring Harbor, the research on genetics of plants was in the capable hands of Anne Lutz. Trained as a cytologist, she carried out important cytological studies and hybridization experiments in plants. Her most notable finding was that Hugo de Vries gigas mutant of Oenothera had doubled the number of chromosomes per cell as compared with the wild type plant. This was not a gene mutation of the kind Thomas Hunt Morgan studied in drosophila. This condition called polyploidy gave Oenothera traits non-Mendelian patterns inheritance which partly accounted for the strange behavior in which de Vries based his book “Mutationstheorie”. The importance of this work was recognized immediately. Eminent Cytologist E.G. Conklin called this an “epoch” making result because it showed that mutations could be due to differences in chromosome number as well as intrachromosomal mutations. After a falling out with Laboratory Director Charles Davenport, she was asked for her resignation in 1910.
Barbara McClintock received her PhD in Botany from Cornell University in 1927, and accepted a full-time research position at the Carnegie Institution of Washington Department of Genetics, Cold Spring Harbor Laboratory in 1941. A pre-eminent cytogeneticist, she developed the first maize genetic linkage map, demonstrated the roles of centromeres and telomeres, and uncovered genetic cross-overing during meiosis.
In 1944, in recognition of her prominence in the field of genetics during this period, McClintock was elected to the National Academy of Sciences—only the third woman to be elected. That same year, she became the first female president of the Genetics Society of America. She was elected its vice-president in 1939. She was the first woman to be awarded the National Medal of Science. She received the Louis and Bert Freedman Foundation Award and the Lewis S. Rosenstiel Award in 1978. In 1981, she became the first recipient of the MacArthur Foundation Grant, and was awarded the Albert Lasker Award for Basic Medical Research the Wolf Prize in Medicine and the Thomas Hunt Morgan Medal by the Genetics Society of America. In 1982, she was awarded the Louisa Gross Horwitz Prize from Columbia University for her research in the "evolution of genetic information and the control of its expression.” Most notably, she received the Nobel Prize for Physiology or Medicine in 1983, the first woman to win that prize unshared, credited by the Nobel Foundation for discovering "mobile genetic elements.” Source: CSHL Archives.
Anna Marie Skalka was a postdoc in Alfred Hershey’s laboratory from 1964-69. Skalka, along with Elizabeth Burgi and Hershey, were the core of the Lambda research group at the laboratory. In Hershey’s group Skalka worked on studying aspects of Lamba and T-5. Her work led to discoveries about the organisms’ replication. She completed her Ph.D. at New York University Medical School in 1964 and came to Cold Spring Harbor Laboratory to continue her graduate work on bacteriophage under Hershey. In 1969 she left for the Roche Institute for Molecular Biology and eventually she turned her attention to retroviruses. Dr. Skalka is now Senior Vice President for Basic Science and director of the Institute for Cancer Research at the Fox Chase Cancer Center in Philadelphia. At Fox Chase, she studies molecular aspects of retroviral replication and hopes to uncover mechanisms of retroviral DNA integration. She has become interested in virally coded integrase, which catalyzes the integration of retroviral DNA into the host cell’s genome. Considering that stable integration of viral DNA into the host cell genome is essential for replication of retroviruses, her studies are important in developing antiviral drugs to treat AIDS.

Eileen White received her Bachelor of Science degree from Rensselaer Polytechnic Institute followed by a Ph.D. in Biology from SUNY Stony Brook. She came to Cold Spring Harbor Laboratory as a Damon Runyon Postdoctoral Fellow in the laboratory of Dr. Bruce Stillman from 1983-1985, and then as a Staff Investigator from 1986-1990. Here she discovered that one of the oncogenes of the DNA tumor virus adenovirus encoded an inhibitor of programmed cell death that was a viral homologue of Bcl-2. She went on to establish that oncogene activation that deregulates cell growth also activates apoptosis, and that inhibition of apoptosis is an important cancer-promoting function. These findings revealed roles for the p53 tumor suppressor in activating apoptosis and suppressing cancer and the Bcl-2-related anti-apoptotic proteins in blocking apoptosis and promoting cancer.
Dr. White is currently Associate Director for Basic Science Rutgers, Cancer Institute of New Jersey.
