Many discoveries in our vast universe can be attributed to amateur astronomers. I remember my first time discovering the moon with a simple telescope. Dr. William Huggins is what we can call an amateur. He is by far one of the wealthiest “amateurs” and influential astronomers of his time. Sir William Huggins was born in Stoke Newington, England on Feb. 7, 1824. Dr. William was born into a wealthy family and spent most of his time not having to work. He took advantage of this and worked with private tutors in the fields of mathematics, physics, and chemistry. Sir Williams was a self-motivated learner. Even at younger ages he showed interest in many studies. He built apparatuses little by little to conduct his experiments. At the age of 28 he was appointed to the Microscopical Society for his studies of plants and animals physiology. During this period of his life, Sir Williams was not much of an Astronomer. He spent much of his time working at his parent’s business located in London.
After retiring from his business at a fairly young age, Sir William was undecided in what his next ventures would be. Would he continue his workings of animals and plants physiology under a microscope or would he explore the heavens? It was not until 1856 that he decided to build his private observatory in Tulse Hill, South London. Dr. William spent most of his lifetime residing within the city of London. He built his private observatory and first started with telescopes, viewing planets such as Mars. He would draw many of his early observations, and it was not until the published works of Gustav Kirchhoff, a physicists and Robert Bunsen, a chemist. Kirchhoff and Bunsen’s published writings were on the analysis and interpretation of spectral lines. B...

...to find a spectrum of a star, he determined that Draco was not formed by the collection of stars, but consisted of hot gases. Dr. Williams observations and experiments with the Spectroscope were even more truly revolutionary by his findings of Doppler Shifts in spectra lines. Using spectral line shifts of a star, he measured the radial velocity of Sirius. For his many accomplishments, Sir Williams was given many awards. His first major award was the Royal Medal from the Royal Society after becoming a fellow. He later earned the Gold Medal in 1867 from the Royal Astronomical Society along with the Rumford Medal (1880), and Copley Medal (1898). After many years and awards in the Royal Society, Sir Williams became their president from 1900 to 1905. Following his retirement, Sir Williams died in Tulse Hill, London following an operation on May 12, 1910 at the age of 86.
...n Francisco, and the Victoria Institute of London, a Fellow of the Royal Microscopical Society of London and a member of the Pacific Astronomical Society of the Pacific. He received a degree in law (LL. D) from Willamette University in 1855 and the honorary degree of Doctor of Divinity (D. D.) from the University of the Pacific in 1876.28 Beyond practicing surgery and medicine, Wythe served as pastor of the Powell Street Methodist Church in San Francisco, found time to present lectures to the community, and record astronomical observation he viewed from the powerful telescope that he placed in his back yard.29 At the Cooper Medical College of San Francisco Dr. Wythe continued in the chair of histology until 1897 and was Professor Emeritus until the time of his passing at the age of 79 at his home in Oakland, California on October 14, 1901 after a long illness. 30
In the mid-nineteenth century, new developments in astronomy were expanding the field at an fast and exciting rate. The Mitchells were aware that the King of Denmark awarded a gold metal to anyone who discovered a "telescopic" comet. No one in America had won that award yet.

One of the most notable contributors to the field of astronomy, never actually worked a telescope. The unjust discrimination against women barred one of the most brilliant astronomers of the 20th century from ever actually viewing the stars she was studying. This did not pose a problem however, as Henrietta Swan Leavitt challenged these notions of female inferiority and ineptitude by entering the predominately male field of astrology and excelling. Henrietta Leavitt's prodigious discovery of the period-luminosity relationship amongst Cepheid variable stars would forever change the way we perceive the universe and known galaxies as well as lay the foundation for astronomers such as Harlow Shapley, Hertzsprung, and Edwin Hubble to expand our knowledge of the universe.
In the time when he was studying medicine, he made a very important science discovery that started his career. One day at church service on Sunday he looked up at a lamp and the lamp was swinging on a long cord back and forth. Its swing was very regular and he used his own pulse to measure the sing. He noticed even as the swing grew shorter the amount of time for a single was the same. Later he went home and conducted many experiments with different lengths and weights. Then he concluded that the string length affected the swing. Soon he created the pendulum and used the same principle to make a pulsilogia which is a device that measures your pulse (Hightower 17-20).

Edwin Hubble was born on November 20, 1889. He graduated from the University of Chicago and served in WWI before he settled down to lead research in the field of astrophysics at Mount Wilson Observatory in California. Edwin Hubble revolutionized the field of astrophysics through the discovery that there are other galaxies outside of the Milky Way as well as the creation of a classification system which is used to identify the various types of galaxies.
'A discovery so unexpected could only have singular circumstances, for it was not due to an astronomer and the marvelous telescope…was not the work of an optician; it is Mr. Herschel, a [German] musician, to whom we owe the knowledge of this seventh principal planet.' (Hunt, 35)
William Harvey was a distinguished physician of the seventeenth century. Harvey was educated by some of the great scientists of his time and was highly knowledgeable of the scientist theories preceding his time. Harvey was greatly intrigued by the views of the ancient Aristotle and developed a number of his own ideas based on Aristotle’s theories. It was from Aristotle’s theory of the primacy of blood that allowed Harvey to make breakthroughs about circulation and generation of animals. His advancements greatly enhanced the study of anatomy. Harvey also revolutionized the means by which science was performed through the use of innovative, investigational techniques. William Harvey became a well-known name in science because he made profound accomplishments that changed the way scientists performed and the way people viewed the human body.
He was one of the first who created the "looker" (now called telescope) by placing two pieces of lenses together. The discovery that placing lenses together can magnify images was made by children who took Lippershey's spectacles and looked at a distant church tower. One of the most influential scientists associated with the telescope has to be Galileo. He took the design and reinvented the telescope into one of the first refractive telescopes we use to this day. Galileo used this great invention to report astronomical facts such as the moon is covered with craters instead of being smooth, the Milky Way is composed of millions of stars, and Jupiter has four moons.
While living on campus at Glasgow University, the family often visited the Netherlands and Germany. They were also quite fond of the Island of Arran, which they often visited. Being so close to water, William Thomson developed a fascination for the sea and the earth’s crust as well. When he was only ten years old he began his studies at Glasgow University. During his years at this institution he received many prizes and awards. He then attended Cambridge University to achieve the credibility he desired. Shortly after, he travelled to Paris to further study thermodynamics. When he was twenty-two, he became a professor of natural philosophy at Glasgow University. There he created a laboratory for physics students to actually experiment instead of just reading about physics in theory (Russell).
Nicholaus Copernicus is one of the most well known astronomers of all time. He is even labeled as the founder of modern astronomy for the proposition of his heliocentric theory (“Nicolaus Copernicus”, Scientists: Their Lives and Works). The heliocentric theory was revolutionary for Copernicus’ time. Copernicus lived during the Renaissance. “The era of the Renaissance (roughly 1400-1600) is usually known for the “rebirth” of an appreciation of ancient Greek and Roman art forms, along with other aspects of classical teachings that tended to diminish the virtually exclusive concentration on religious teachings during the preceding centuries of the “Dark Ages.” New thinking in science was also evident in this time…” This time period became known as the scientific revolution (“Copernicus: On The Revolutions Of Heavenly Bodies). In other words, old ideas were revived in the arts and other means and less emphasis was placed o...
Since the beginning of astronomy, astronomers had a unanimous goal: to see farther, better and in greater details.
