Patrick Thaddeus is Robert Wheeler Willson Professor of Applied Astronomy Emeritus at Harvard University. He is best known for mapping the Milky Way galaxy in Carbon Monoxide and is responsible for the construction of the CfA 1.2 m Millimeter-Wave Telescope.
Thaddeus graduated from University of Delaware in 1953 with a Bachelor of Science degree. He was awarded a Fulbright Fellowship through which he attended the University of Oxford, graduating with a Master's degree in theoretical physics in 1955. His doctoral work was at Columbia University, where he earned his Ph.D. under Charles Hard Townes in 1960 with a thesis titled Beam Maser Spectroscopy.
|In the early 1970s, an astronomer at the Goddard Institute of Space Studies in New York named Patrick Thaddeus shattered centuries of precedent in the field of astronomy and bucked a trend dating all the way back to Galileo when he decided that, in order to proceed on a modest project to map the entire Milky Way, he simply did not need and in fact refused to use a larger telescope made available for his research. He wanted a small one. In an era made conspicuous by bigger, more sophisticated, and (need it be added?) more expensive telescopes, Thaddeus insisted on a small and relatively inexpensive instrument, which he and his colleagues proceeded to build from scratch.|

After earning his doctorate, Thaddeus stayed at Columbia University as a research associate in the Columbia Radiation Laboratory until 1961, when he took a position working for NASA at the Goddard Institute for Space Studies, where he remained until 1986. He also taught at Columbia University during that period, from 1965 until 1986. It was during his time at Columbia that the CfA 1.2 m Millimeter-Wave Telescope was built. In 1986, Thaddeus (along with the 1.2 meter telescope and other scientists on the team) moved to Harvard, where he remained for the rest of his teaching career and remains Professor Emeritus.
Thaddeus held a few other teaching positions during his career at institutions including State University of New York, Stony Brook (1966–1967), University of California, Berkeley (1968), and University of Cambridge (1983–1984).
Thaddeus and his colleagues designed a radio telescope custom-built for the task of mapping the entire Milky Way in CO. The 1.2 meter Millimeter-Wave Telescope was designed with a relatively small dish and consequently a relatively large beamwidth of about 1/8 degree, which can be likened to a wide-angle lens. With this new instrument, it suddenly became possible to map large stretches of sky in relatively small amounts of time. The telescope is nicknamed "The Mini" because of its unusually small size. Together, "The Mini" and its twin in Chile have obtained what is by far the most extensive, uniform, and widely-used Galactic survey of interstellar carbon monoxide (CO).
Thaddeus married the former Janice Farrar (daughter of John Chipman Farrar and Margaret Petherbridge Farrar) in 1963. Janice Farrar Thaddeus was a scholar, poet, editor, and former Harvard lecturer in English; she died in 2002 at the age of 68. They have two children: Eva and Michael.
Thaddeus has authored or co-authored more than three hundred research papers and more than twenty invited papers in astronomy and physics.

|"Until the war, astronomy was confined to about an octave, or factor of three, in wavelength, centered on the visual. And what we've done since then is just explode across the whole spectrum, so that now astronomy goes from very, very long radio wavelengths, meters and tens-of-meters long, down to gamma rays. And so to a great degree what we've been doing is just explode into these empty regions of frequency space, and in many ways we're still really just doing the survey work. Finding out what's there, and doing the basic mapping. Every time you go to a new wavelength band, the general rule is that you find a completely different aspect of nature in that information."|
