TheAmerican Meteor Society, Ltd. (AMS) is anon-profit scientific organization established to encourage and support the research activities of both amateur and professionalastronomers who are interested in the field of meteor astronomy. Its affiliates observe, monitor, collect data on, study, and report onmeteors,meteor showers, meteoric fireballs, and related meteoric phenomena.

The society publishes observations and scientific interpretations quarterly inMeteor Trails, The Journal of American Meteor Society. Once per year they give theAmerican Meteor Society Award to a person who has contributed to research on meteors. They also provide an annual research grant to a student of SUNY-Geneseo who has contributed to meteor research or to the AMS.^[1]

The society was founded in 1911 byCharles P. Olivier of theLeander McCormick Observatory. The initial enrollment was fifteen members. These were recruited by Olivier by letter. The first paper based on the observations of the members appeared in theAstronomical Journal in 1912, describing theη Aquaridmeteor shower.^[2][3] In 1926, Olivier began to publish meteor notes from the society on a nearly monthly basis inPopular Astronomy magazine under the title "Monthly Notes".^[4] This continued until his editor, Curvin H. Gingrich, died.^[5]

Some time before 1932, Olivier appointed regional directors to facilitate the data collection for the society. A director was appointed to the Pacific Northwest region in 1932. Initially this consisted of Washington state and Oregon, but later came to include the western provinces of Canada plus Idaho and Montana. In 1938, the Canadian provinces were withdrawn from the society, while California was added. This western division was headquartered at theUniversity of Oregon in Eugene.^[6]

In 1960, Olivier published the first catalogue of hourly meteor rates based upon the data collected by the society members from 1901 to 1958. The second catalogue was published in 1965, which included data up to 1963.^[7]

During the late 1970s, David Meisel became Executive Director of the society. Its headquarters were relocated toGeneseo, New York. The society research was expanded to include radio meteor studies, then spectroscopy of meteors.^[8][9]
