Charles Greeley Abbot Net Worth

Charles Greeley Abbot was an American astrophysicist born in Wilton, United States on May 31, 1872. He was a talented inventor from a young age, and was hired as an assistant by the famous physicist, Samuel Langley, at the Smithsonian Astrophysical Observatory. Abbot conducted research on solar radiations and established the value of the solar constant. He eventually became the fifth Smithsonian Secretary and the first one to retire from his post. Abbot was also involved in a lifelong project to establish the fact that the Sun’s energy output varies and it has a measurable effect on the Earth’s weather. His most famous contribution is his research on the solar constant, which led to the development of numerous patented solar energy devices.

Biography/Timeline

1894

He would graduate in 1894 with a Master of Science in physics. Abbot would meet Samuel P. Langley on MIT campus when Langley visited seeking an assistant. In 1895, he would start working as an aid at the Smithsonian Astrophysical Observatory.

1900

While at the Smithsonian Astrophysical Observatory (SAO), Abbot would work under Samuel P. Langley. Langley would go on to change his focus from solar radiation to aeronautics, with Abbot taking over solar radiation research. Abbot would participate in many expeditions. In 1900 he, along with Langley, would travel to Wadesboro, North Carolina to observe a solar eclipse, followed by another eclipse expedition to Sumatra in 1901. During his expedition experiences he would also travel to Algeria, Egypt, South Africa, Australia, and other countries, often in partnership with the National Geographic Society. Abbot would become acting Director of SAO in 1906 and in 1907, Abbot became the Director of the Smithsonian Astrophysical Observatory, following the death of Samuel P. Langley. While Langley was still Director, he had visited Mount Whitney, and decided it would be a great place for an observatory. Abbot secured funding for the observatory and it was built in 1909. As Director, a position he would hold until his retirement, Abbot would open the Radiation Biology Laboratory in 1929, to study radiation effects on plants, and other organisms. This helped to develop the first wave of biophysics researchers in the United States.

1910

An instrumentalist, he invented the solar cooker, which was first built at Mount Wilson Observatory, the solar boiler, and held fifteen other patents related to solar Energy. For his research and contributions to the sciences, Abbot was awarded a Henry Draper Medal in 1910 and a Rumford Medal in 1916.

1918

Abbot would become the Assistant Secretary at the Smithsonian Institution in 1918, upon the death of Frederick W. True. In his role as Assistant Secretary he would oversee the Smithsonian Institution Libraries, the International Exchange Service, and the SAO. He also co-created the Smithsonian Scientific Series books, which helped raise funds for the Smithsonian.

1928

Ten years later, on January 10, 1928, he became the fifth Secretary of the Smithsonian after the death of Charles Doolittle Walcott. Abbot would also maintain his position as Director of the Astrophysical Observatory. In 1927, Walcott had finalized the Smithsonian's strategic plan, which Abbot took on responsibility for upon his election as Secretary. The Smithsonian began a capital campaign in 1929, coinciding with the start of the Great Depression. During this tenure, Abbot oversaw the Smithsonian's participation in Works Progress Administration projects, including the Federal Art Project. Projects included new buildings and artwork at the National Zoo, and the start of the Smithsonian's first media project, a radio show called The World is Yours. The program would be ceased in 1942 due to World War II. In the 1930s an expansion was approved for the National Museum of Natural History building, which would not begin until the 1960s. The Institute for Social Anthropology was also transferred to the Smithsonian during this time. While Secretary, Abbot would fail to acquire the National Gallery of Art for the Smithsonian. Abbot's role in the United States National Museum was also minimal, and was under the primary care of Assistant Secretary Alexander Wetmore.

1944

He was the first Smithsonian Secretary to retire, ending his tenure on July 1, 1944. Following retirement, he was awarded Secretary Emeritus status and proceeded to continue his research work. The first Smithsonian holiday party would be held during his tenure. At the party, Abbot sang and played the cello for the partygoers. While in Washington, he was a deacon at the First Congregational Church. He also played tennis frequently at the former tennis courts at the Smithsonian Castle.

1953

Abbot began his astrophysics research focusing on solar radiation before proceeding to chart cyclic patterns found in solar variations. With this research he hoped to track solar constant in order to make weather pattern predictions. He believed that the sun was a variable star which effected the weather on Earth, which was criticized by many contemporaries. In 1953, he discovered a connection between solar variations and planetary climate. This discovery allowed general climate patterns to be predicted 50 years in advance. He did field work at the Smithsonian Institution Shelter, which was built during his tenure as Director at SAO, Lick Observatory, and Mount Wilson Observatory. At Lick, he worked with W.W. Campbell. To fight critics, Abbot would utilize balloons with pyrheliometers installed on them for measurements. He was the first scientist in America to do so, with the balloons reaching upwards of 25 kilometers. One balloon returned data that allowed Abbot to determine the solar constant at the highest point of the Earth's atmosphere. Later in his research career, he turned his focus on solar Energy use.

1955

On May 31, 1955, the Smithsonian held a birthday party for Abbot, marking his 83rd birthday and his 60th year of association with the Smithsonian. The event was held at the Smithsonian Castle and a bronze bust of Abbot, by Alicia Neatherly, was presented, and donated to the National Gallery of Art. Charles Greeley Abbot died, at age 101 in Maryland, on December 17, 1973. The American Solar Energy Society has an award named in Abbot's honor, which is awarded for contributions to solar Energy research.
