His father, Christian Bohr, was a renowned professor of physiology at the University of Copenhagen. Several outreach organisations and activities have been developed to inspire generations and disseminate knowledge about the Nobel Prize. Theorized: That electrons absorb and emit radiation of fixed wavelengths when jumping between fixed orbits around a nucleus. To cite this section The second of three children, the Bohr family was a very successful one. Another physicist, by the name of Albert Einstein, didn’t fully see eye to eye with all of Bohr's assertions, and their talks became renowned in scientific communities. Niels Henrik David Bohr was born on October 7, 1885 in Copenhagen, Denmark to Christian and Ellen Adler Bohr. Niels Bohr Nationality: Danish Discovery Year: 1913 Louis de Broglie.

In 1957, Bohr received the Atoms for Peace Award for his trailblazing theories and efforts to use atomic energy responsibly. Mixed reactions followed Bohr’s 1913 publication, but Bohr’s model showed that electrons lined up in regular patterns when light was emitted by real hydrogen atoms. With Adolf Hitler's rise in power, Bohr was able to offer German Jewish physicists refuge at his institute in Copenhagen, which in turn led to travel to the United States for many. When jumping from one orbit to another with lower energy, a light quantum is emitted. Niels Bohr adapted Ernest Rutherford's nuclear model. Bohr’s own research led him to theorize in a series of articles that atoms give off electromagnetic radiation as a result of electrons jumping to different orbit levels, departing from a previously held model espoused by Ernest Rutherford. Then in 1912, Niels Bohr was working for J.J. Thomson. Bohr's theory could explain why atoms emitted light in fixed wavelengths. Niels Bohr was an accomplished physicist who came up with a revolutionary theory on atomic structures and radiation emission.
