During his second year at the university he took a course in astronomy. He was also given a room at the Washburn Observatory and worked nights as an assistant.[1] These would serve to shape his interest in astronomy. He studied astronomy under George Comstock.[2] In his second year as a graduate student he was offered a Hearst fellowship at the Lick Observatory, which he accepted, arriving in 1892. In 1893, however, the fellowship funds were re-committed to an eclipse expedition to Chile, so he had to depart.
He would graduate with a B.S. degree in 1891 with distinction, and become a member of Phi Beta Kappa.[1][2] After graduation that same year he visited his brother living in California, which made him interested in Lick Observatory.[2]
Career

From 1893 until 1898 he worked at the Detroit Observatory, where he studied variable stars and comets. By 1897, he gained his Sc.D. from the University of Michigan with a thesis on the "Orbit of Psyche".[2][4] In 1896, he spent a year on-leave to travel through Germany, visiting major observatories in Berlin, Leipzig, and Munich.[2]
After his return from his travels he began teaching at the University of California, Berkeley, under Armin Otto Leuschner.[2] He was later appointed director of the International Latitude Station at Ukiah, California. While there he developed an interest in geodesy, particularly seismology.
Townley was a member of the Astronomical Society of the Pacific during its early years[1] and served as its president in 1916, and also spent time as director and on the publication committee. He also joined the Seismological Society, and served at various times as president, secretary-treasurer, and editor of the society journal.
In 1911 he became an assistant professor at Stanford University. By 1918, he became full professor, and would remain in that position until his retirement in 1932, thereafter becoming professor emeritus.[2]

Toward the end of his life he became an invalid, although he remained mentally alert until he died. He died March 18, 1946, at Stanford, California.[1]
During his career he published roughly 100 academic papers, and edited the contributions of many others.[2] He was widely recognized for his editorial skills.[2]
The crater Townley on the Moon is named after Townley.
Private life
He married Frances May Wright on January 7, 1895, in Oregon.[5] Together they had three daughters and at the time of retirement lived in Palo Alto, California.[3]
His daughter Lucile Townley Clark, married architect, Birge Clark.[3] Birge Clark's father was architect and Stanford University design professor Arthur Bridgman Clark who designed the Townley's residence at 613 Salvatierra (now 661 Cabrillo Avenue; built 1921) in Stanford, California.[6] Another daughter, Isabel Townley Marx married the son of Stanford University mechanical engineering professor Guido Hugo Marx.[7][8]
