David Scott – the First Person to Drive on the Moon

David Scott – the First Person to Drive on the Moon

On June 6, 1932, American engineer, test pilot and NASA astronaut David Randolph Scott was born. Scott became the seventh person to walk on the Moon as commander of the Apollo 15 mission, the fourth human lunar landing. Moreover, he was the first to drive a wheeled vehicle on the moon on 31 July 1971. David Scott was born on Randolph Field near San Antonio, Texas, USA. Scott was educated…
Ruth Benedict and Cultural Anthropology

Ruth Benedict and Cultural Anthropology

On June 5, 1887, American anthropologist and folklorist Ruth Fulton Benedict was born. Benedict’s theories had a profound influence on cultural anthropology, especially in the area of culture and personality. Her major contribution to anthropology, compares Zuñi, Dobu, and Kwakiutl cultures in order to demonstrate how small a portion of the possible range of human behaviour is incorporated into any one culture. Ruth Fulton Benedict first attended lectures at the New…
Beno Gutenberg and the Earth’s Interior

Beno Gutenberg and the Earth’s Interior

On June 4, 1889, German-American seismologist Beno Gutenberg was born. Gutenberg is noted for his analyses of earthquake waves and the information they furnish about the physical properties of the Earth’s interior. He was a colleague and mentor of Charles Francis Richter at the California Institute of Technology and Richter’s collaborator in developing the Richter magnitude scale for measuring an earthquake’s magnitude. Beno Gutenberg was born in Darmstadt, Germany, the…
Raymond Pearl and Biometry

Raymond Pearl and Biometry

On June 3, 1879, American biologist Raymond Pearl was born. Pearl is regarded as one of the founders of biogerontology. Moreover, he is one of the founders of biometry, the application of statistics to biology and medicine. He also pioneered studies in longevity, changes in world population, and genetics. Raymond Pearl earned his PhD in zoology for his work on the behavior of planarians from the University of Michigan. Along…
Clair Cameron Patterson and the exact Age of the Earth

Clair Cameron Patterson and the exact Age of the Earth

On June 2, 1922, American geochemist Clair Cameron Patterson was born. Patterson developed the uranium–lead dating method into lead–lead dating and, by using lead isotopic data from the Canyon Diablo meteorite, he calculated an age for the Earth of 4.55 billion years; a figure far more accurate than those that existed at the time and one that has remained largely unchanged since 1956. Clair Patterson was born in Mitchellville, Iowa,…
Hugo Münsterberg and Applied Psychology

Hugo Münsterberg and Applied Psychology

On June 1, 1863, German-American psychologist Hugo Münsterberg was born. Münsterberg was one of the pioneers in applied psychology, extending his research and theories to Industrial/Organizational, legal, medical, clinical, educational and business settings. He was a forerunner in the field of behaviorism: in theoretical psychology, his “action theory” defined attention in terms of the openness of the nerve paths to the muscles of adjustment. Hugo Münsterberg highly supported the idea…
Chien-Shiung Wu and the Conservation of Parity

Chien-Shiung Wu and the Conservation of Parity

On May 31, 1912, Chinese-American experimental physicist Chien-Shiung Wu was born. Wu is best known for conducting the Wu experiment, which contradicted the hypothetical law of conservation of parity. This discovery resulted in her colleagues Tsung-Dao Lee and Chen-Ning Yang winning the 1957 Nobel Prize in physics, and also earned Wu the inaugural Wolf Prize in Physics in 1978. Her expertise in experimental physics evoked comparisons to Marie Curie. Chien-Shiung…
Hannes Alfvén – the Father of Plasma Physics

Hannes Alfvén – the Father of Plasma Physics

On May 30, 1908. Swedish electrical engineer, plasma physicist, and Nobel laureate Hannes Alfvén was born. Alfvén won the 1970 Nobel Prize in Physics for his work on magnetohydrodynamics (MHD). He described the class of MHD waves now known as Alfvén waves. Alfvén made many contributions to plasma physics, including theories describing the behavior of aurorae, the Van Allen radiation belts, the effect of magnetic storms on the Earth’s magnetic field, the terrestrial magnetosphere, and…
Sir David Bruce and the Malta Fever

Sir David Bruce and the Malta Fever

On May 29, 1855, Scottish pathologist and microbiologist Sir David Bruce was born. Bruce investigated Malta fever (later called brucellosis in his honour) and African trypanosomiasis (sleeping sickness in humans and nagana in animals). He discovered the first protozoan parasite transmitted by insects, which was later named Trypanosoma brucei after him. David Bruce was born in Melbourne, Australia, to David Bruce, a Scottish engineer and his wife Jane Russell Hamilton,…
Alfred Nier and Mass Spectroscopy

Alfred Nier and Mass Spectroscopy

On May 28, 1911, American physicist Alfred Otto Carl Nier was born. Nier pioneered the development of mass spectrometry. He was the first to use mass spectrometry to isolate uranium-235 which was used to demonstrate that 235U could undergo fission and developed the sector mass spectrometer configuration now known as Nier-Johnson geometry. Alfred Otto Carl Nier attended the University of Minnesota and graduated in electrical engineering in 1931. Nier decided…
