Study Notes
Linus Pauling
- Chemist, winner of two Nobel Prizes (Chemistry and Peace)
- Early proponent of quantum mechanics in chemistry
- Published The Nature of the Chemical Bond (1939) – influential chemistry text
- Developed five rules for ionic crystal structure and described atomic orbitals in covalent compounds
- Covalent bonding involves electron sharing, position flexibility
Kathleen Lonsdale
- Developed X-ray techniques to study chemical compounds
- Determined benzene's hexagonal carbon ring structure
- Used X-ray crystallography to analyze bladder stones and relaxant drugs
- Became one of two women fellows at the Royal Society, London (previously men-only)
John von Neumann
- Hungarian-born mathematician
- Developed early high-speed electronic digital computers
- Worked at Princeton University from 1930
- Created a model for computer architecture now called von Neumann architecture, allowing programs and data storage
- Helped develop weather predictions
Wendell Stanley
- Determined virus molecular structures using X-ray diffraction
- Shared 1946 Nobel Prize in Chemistry for research on tobacco mosaic virus
- Helped develop influenza vaccine during World War II
- Crystallized polio virus, a key step in creating a polio vaccine
Rita Levi-Montalcini
- Faced challenges with her father and societal expectations regarding women's roles
- Studied medicine at University of Turin; later made major discoveries about nerve growth factors (NGFs)
- Moved to the US in 1947 and became a professor
- NGFs are key factors in many diseases and were later recognized
- Won (1986) Nobel Prize in Physiology or Medicine
- Worked with Stanley Cohen
Ruby Payne-Scott
- Australian radio physicist
- Worked with the radiophysics laboratory in the 1940s/50s
- One of only two women physicists
- Developed radar for Australia's coastline (WWII)
- Measured radio emissions from the Sun.
- Worked with a team to develop a method to measure radio emissions
Jonas Salk
- American virologist
- Developed the first safe and effective polio vaccine
- The vaccine used killed virus, not live
- Large-scale trials (1954) were successful
- Vaccine was effective but not long-lasting
- Polio vaccine was part of a race with Albert Sabin
Lyman Spitzer Jr.
- Renowned US astrophysicist
- First scientist to conceptualize space telescopes
- Highlights the problem of detecting non-visible radiation through Earth's atmosphere
- Proposed to put telescopes in space
- Campaign for space telescope lead to funding for Hubble Space Telescope
Robert Edwards
- British physiologist
- Developed "test-tube" pregnancy techniques
- Worked on fertilization (1955)
- Spent 20 years creating artificial fertilization methods (outside the body)
- Developed methods along with Patrick Steptoe resulting in the world's first in vitro fertilization (IVF) baby in 1978
- Awarded 2010 Nobel Prize for Physiology or Medicine.
