5 Scientists Too Smart for Their Time
SciShow・2 minutes read
Alfred Wegener proposed the theory of continental drift, facing rejection until the 1960s when plate tectonics was accepted. Rosalind Franklin's x-ray crystallography led to the discovery of DNA's double helix, but her contributions were overshadowed by Watson and Crick.
Insights
- Alfred Wegener faced significant resistance and ridicule from the scientific community for his theory of continental drift, which was not widely accepted until the 1960s when plate tectonics became recognized.
- Rosalind Franklin, despite her crucial work in discovering the double helical structure of DNA through x-ray crystallography, was overshadowed by James Watson and Francis Crick, who used her data without permission to announce their findings.

Pioneers in Science: Wegener, Franklin, Maxwell
- Alfred Wegener, born in 1880 in Germany, was a pioneer in meteorology and geophysics, known for his theory of continental drift.
- Wegener's theory, proposed in 1914, suggested that all land masses were once part of a single continent, leading to the concept of plate tectonics.
- Despite his groundbreaking theory, Wegener faced ridicule and rejection from the scientific community, with many dismissing him as a weatherman.
- Wegener's theory was not widely accepted until the 1960s when plate tectonics became a recognized scientific concept.
- Rosalind Franklin, a scientist who contributed to the discovery of the structure of DNA, was overshadowed by James Watson and Francis Crick.
- Franklin's expertise in x-ray crystallography led to the groundbreaking discovery of the double helical structure of DNA.
- Franklin's crucial work on DNA structure was overshadowed when Watson and Crick used her data without her permission to announce their findings.
- Henrietta Swan Leavitt, an astronomer at the Harvard College Observatory, made significant contributions to measuring stellar distances despite facing gender discrimination.
- James Clerk Maxwell, a Scottish physicist born in 1831, made groundbreaking discoveries in electromagnetism and the kinetic theory of gases.
- Maxwell's equations unified electricity and magnetism, laying the foundation for modern physics and technologies like radio and television.

Pioneering Women in Astronomy and Computing
- Henrietta Leavitt studied astronomy at Radcliffe College but couldn't pursue a paying career, so she volunteered at Harvard College Observatory.
- Working with other women known as computers, Leavitt cataloged Cepheid variables in the Small Magellanic Cloud, discovering a correlation between star size and luminosity.
- Leavitt's groundbreaking discovery, known as Leavitt's Law, allowed for the measurement of Cepheid stars millions of light years away, revolutionizing astronomy.
- Despite her significant contributions, Leavitt was not allowed to operate telescopes and passed away before receiving recognition, including a Nobel Prize nomination.
- Ada Lovelace, mentored by Charles Babbage, is considered the first computer programmer, envisioning machines capable of manipulating symbols and numbers, setting the foundation for modern computing.
