About this collection

Dr. Clyde W. Tombaugh was born in Streator, Illinois in 1906. He was not long removed from the family farm in southwestern Kansas when he discovered Pluto in 1930 while working at Lowell Observatory in Flagstaff, Arizona. As a young man and amateur astronomer, Tombaugh began building his own telescopes. He eventually sent drawings to Lowell Observatory hoping for suggestions. Instead, the observatory was so impressed with his work that they eventually offered him a job, changing the course of his life forever.

 

Tombaugh earned a master's degree in astronomy from the University of Kansas and eventually received an honorary doctorate from Northern Arizona University. He enjoyed a long and industrious career as an astronomer, spending time at places like UCLA and White Sands Proving Ground in New Mexico before eventually helping to establish the NMSU Astronomy Department in 1970. He served as NMSU faculty and faculty emeritus for over twenty years until his death in 1997.

 

The Clyde W. Tombaugh Papers digital collection is a work in progress. At the present time it consists of selected materials from Tombaugh's life and career: family and other personal correspondence; professional correspondence; astronomical research and writings; and other items collected over the course of his life. The collection also contains large format items such as star charts, maps, and examples of his drawings. Click below to browse the document series.
