36-678: Astronomy award The Rittenhouse Medal is awarded by the Rittenhouse Astronomical Society for outstanding achievement in the science of Astronomy. The medal was one of those originally minted to commemorate the Bi-Centenary of the birth of David Rittenhouse on April 8, 1932. In 1952 the Society decided to establish a silver medal to be awarded to astronomers for noteworthy achievement in astronomical science. The silver medal
72-556: A Wednesday evening salon meeting with Benjamin Franklin, Francis Hopkinson, Pierre Eugene du Simitiere and others. Thomas Jefferson wrote that he would rather attend one of these meetings "than spend a whole week in Paris." Rittenhouse was married twice. He married Eleanor Coulston February 20, 1766, and they had two daughters: Elizabeth (born 1767) and Ester (born 1769). Eleanor died February 23, 1771, at age 35 from complications during
108-438: A few weeks per year. Analysis of observed phenomena, along with making predictions as to the causes of what they observe, takes the majority of observational astronomers' time. Astronomers who serve as faculty spend much of their time teaching undergraduate and graduate classes. Most universities also have outreach programs, including public telescope time and sometimes planetariums , as a public service to encourage interest in
144-475: A large scale did not begin until 1793. Rittenhouse resigned from the Mint on June 30, 1795, due to poor health. In 1871 Congress approved a commemorative medal in his honor. In 1781 Rittenhouse became the first American to sight Uranus . In 1785 Rittenhouse made perhaps the first diffraction grating using 50 hairs between two finely threaded screws, with an approximate spacing of about 100 lines per inch. This
180-738: A system of stars or a galaxy to complete a life cycle, astronomers must observe snapshots of different systems at unique points in their evolution to determine how they form, evolve, and die. They use this data to create models or simulations to theorize how different celestial objects work. Further subcategories under these two main branches of astronomy include planetary astronomy , astrobiology , stellar astronomy , astrometry , galactic astronomy , extragalactic astronomy , or physical cosmology . Astronomers can also specialize in certain specialties of observational astronomy, such as infrared astronomy , neutrino astronomy , x-ray astronomy , and gravitational-wave astronomy . Historically , astronomy

288-577: The American Astronomical Society , and this was another factor in being chosen to study Venus. Throughout his life he had the honour to serve in many different clubs and committees. In 1768, Rittenhouse was elected to membership in the American Philosophical Society . He served as librarian, secretary, and after Benjamin Franklin 's death in 1790, he became Vice president then served as president of
324-528: The Mason–Dixon line to the southwest corner of Pennsylvania. When Rittenhouse's work as a surveyor ended, he resumed his scientific interests. In 1768, the same year that he became a member of the American Philosophical Society , Rittenhouse announced plans to observe a pending transit of Venus across the Sun from several locations. The American Philosophical Society persuaded the legislature to grant £100 towards
360-527: The formation of galaxies . A related but distinct subject is physical cosmology , which studies the Universe as a whole. Astronomers usually fall under either of two main types: observational and theoretical . Observational astronomers make direct observations of celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate models of things that cannot be observed. Because it takes millions to billions of years for

#1732786975085432-547: The Pennsylvania–Maryland border. Later Rittenhouse helped establish the boundaries of several other states and commonwealths both before and after the Independence, including the boundaries between New Jersey, New York and Pennsylvania. In 1763 Mason and Dixon began a survey of the Pennsylvania–Maryland border, but this work was interrupted in 1767. In 1784 Rittenhouse and Andrew Ellicott completed this survey of
468-545: The PhD level and beyond (as of 2024). Contrary to the classical image of an old astronomer peering through a telescope through the dark hours of the night, it is far more common to use a charge-coupled device (CCD) camera to record a long, deep exposure, allowing a more sensitive image to be created because the light is added over time. Before CCDs, photographic plates were a common method of observation. Modern astronomers spend relatively little time at telescopes, usually just
504-584: The Solar System. In recognition of the achievement, the College of New Jersey granted Rittenhouse an honorary degree. The college then acquired ownership of the orrery. Rittenhouse made a new, more advanced model which remained in Philadelphia. The State of Pennsylvania paid Rittenhouse £300 as a tribute for his achievement. One of Rittenhouse's hands or helpers with the project was Henry Voigt ,
540-493: The birth of their third baby, who died at birth. David married his second wife Hannah Jacobs in late 1772. They had an unnamed baby, who died at birth in late 1773. Hannah survived David by more than three years, dying in late 1799. David's grandson, the son of Ester, was named David Rittenhouse Waters. David Rittenhouse made many breakthroughs of importance to the United States. During the first part of his career he
576-652: The clockmaker and Chief Coiner under Rittenhouse at the mint. Voigt later repaired the orrery in 1806 and was an earlier co-inventor of the first practical steamboat with John Fitch . David Rittenhouse was treasurer of Pennsylvania from 1777 to 1789, and with these skills and the help of George Washington , he became the first director of the United States Mint . On April 2, 1792, the United States Mint opened its doors, but would not produce coins for almost four months. Rittenhouse believed that
612-421: The core sciences, a competency examination, experience with teaching undergraduates and participating in outreach programs, work on research projects under the student's supervising professor, completion of a PhD thesis , and passing a final oral exam . Throughout the PhD training, a successful student is financially supported with a stipend . While there is a relatively low number of professional astronomers,
648-453: The design of a coin reflected the sophistication and culture of a country. The first coins were made from flatware that was provided by George Washington on the morning of July 30, 1792. The coins were hand-struck by Rittenhouse, to test the new equipment, and were given to Washington as a token of appreciation for his contributions to making the United States Mint a reality. The coin design had not been approved by Congress . Coin production on
684-460: The distance from Earth to the Sun to be 93 million miles. (This is the approximate average distance between Earth and the Sun.) The published report of the transit was hailed by European scientists, and Rittenhouse would correspond with famous contemporary astronomers, such as Jérôme Lalande and Franz Xaver von Zach . In 1770, Rittenhouse completed an advanced orrery ; that is, a mechanical model of
720-549: The environment and climate of North America had stunted the intellect of peoples living there both native and European. A fictionalized version of David Rittenhouse, portrayed by Armin Shimerman , appeared in the tenth episode of the first season of the NBC television series Timeless (2016–2018). The series re-imagines Rittenhouse as the founder of a sinister secret society that bears his name. Astronomer An astronomer
756-474: The field is popular among amateurs . Most cities have amateur astronomy clubs that meet on a regular basis and often host star parties . The Astronomical Society of the Pacific is the largest general astronomical society in the world, comprising both professional and amateur astronomers as well as educators from 70 different nations. As with any hobby , most people who practice amateur astronomy may devote

#1732786975085792-489: The field. Those who become astronomers usually have a broad background in physics, mathematics , sciences, and computing in high school. Taking courses that teach how to research, write, and present papers are part of the higher education of an astronomer, while most astronomers attain both a Master's degree and eventually a PhD degree in astronomy, physics or astrophysics . PhD training typically involves 5-6 years of study, including completion of upper-level courses in
828-694: The majority of their time working on research, although they quite often have other duties such as teaching, building instruments, or aiding in the operation of an observatory. The American Astronomical Society , which is the major organization of professional astronomers in North America , has approximately 8,200 members (as of 2024). This number includes scientists from other fields such as physics, geology , and engineering , whose research interests are closely related to astronomy. The International Astronomical Union comprises about 12,700 members from 92 countries who are involved in astronomical research at

900-419: The planet Venus chose Rittenhouse to study the transit path of Venus in 1769 and its atmosphere. Rittenhouse was the perfect person to study the mysterious planet, as he had a personal observatory on his family farm. "His telescope, which he made himself, utilized grating intervals and spider threads on the focus of the telescope." His telescope is very similar to some modern-day telescopes. Rittenhouse served on
936-426: The purchase of new telescopes, and members volunteered to staff half of the 22 telescope stations when the event arrived. The transit of Venus occurred on June 3, 1769. Rittenhouse's great excitement at observing the infrequently occurring transit of Venus (for which he had prepared for a year) resulted in his fainting during the observation. In addition to the work involved in the preparations, he had also been ill
972-559: The rural area of New Jersey , rather than in Philadelphia , which was seeking to be one of the important centers of the 18th century enlightenment and for the study of "natural philosophy" such as astronomy. Both of these orreries still exist, with each being held by their original recipients: one in the library of the University of Pennsylvania and the other at Peyton Hall of Princeton University. Astronomers who had been studying
1008-604: The society until 1796. He was elected a Fellow of the American Academy of Arts and Sciences in 1782. Another one of his interests was the Royal Society of London of which he was a member. It was very rare for an American to be a member of this exclusive British society. In 1786, Rittenhouse built a new Georgian-style house on the corner of 4th and Arch streets in Philadelphia, next to an octagonal observatory he had already built. At this house, he maintained
1044-591: The solar system, the first for The College of New Jersey, now Princeton University , and the second for the College of Philadelphia, now the University of Pennsylvania . Rittenhouse was prevailed upon to construct the second orrery by his friend, the Reverend William Smith, the first provost of the College of Philadelphia, who was upset that he would deliver such a device to a college located in
1080-500: The week before the transit. Lying on his back beneath the telescope, trained at the afternoon sun, he regained consciousness after a few minutes and continued his observations. His account of the transit, published in the American Philosophical Society's Transactions , does not mention his fainting, though it is otherwise meticulous in its record and documented. Rittenhouse used the observations to calculate
1116-631: Was self-taught from his family's books, and he showed great ability in science and mathematics. When David was 13 years of age, he had mastered Isaac Newton 's laws of motion and gravity . At roughly age 17, David constructed a clock with wooden gears. At the age of 19, he started a scientific instrument shop at his father's farm in what is now Valley Forge Medical Center and Hospital, located in East Norriton Township, Pennsylvania . His skill with instruments, particularly clocks, led him to construct two orreries to scale models of

1152-662: Was a surveyor for Great Britain, and later served in the Pennsylvania government. His 1763–1764 survey of the Delaware–Pennsylvania border was a 12-mile (19 km) circle about the Court House in New Castle, Delaware, to define the northern border of Delaware. Rittenhouse's work was so precise and well-documented that it was incorporated without modification into Charles Mason and Jeremiah Dixon 's survey of
1188-618: Was an American astronomer , inventor, clockmaker , mathematician, surveyor , scientific instrument craftsman, and public official. Rittenhouse was a member of the American Philosophical Society and the first director of the United States Mint . Rittenhouse was born on April 8, 1732, in Rittenhousetown , in Germantown , along Paper Mill Run , a small tributary of the Wissahickon Creek . His great-grandfather, who
1224-498: Was born in the Rhineland , emigrated to Pennsylvania in 1688. When his uncle, William Rittenhouse, died, David inherited his uncle's carpentry tools and instructional books. At a young age, David showed a high level of intelligence by creating a working scale model of his great-grandfather William Rittenhouse 's paper mill. He built other scale models in his youth, like a working waterwheel. David never attended elementary school—he
1260-498: Was more concerned with the classification and description of phenomena in the sky, while astrophysics attempted to explain these phenomena and the differences between them using physical laws . Today, that distinction has mostly disappeared and the terms "astronomer" and "astrophysicist" are interchangeable. Professional astronomers are highly educated individuals who typically have a PhD in physics or astronomy and are employed by research institutions or universities. They spend
1296-533: Was roughly the same technique that Joseph von Fraunhofer used in 1821 for his wire diffraction grating. Other notable events in Rittenhouse's life include: In his book Notes on the State of Virginia , Thomas Jefferson listed Rittenhouse alongside Benjamin Franklin and George Washington as examples of New World genius when disputing French naturalist Georges-Louis Leclerc, Comte de Buffon 's claim that
