Approximately 2000 stellar parallaxes were determined from the 70 In 1903 the Carnegie Institution of Washington made it possible for Yerkes Observatory of the University of Chicago (Schlesinger 1927), a 30-inch photographic refractor specifically for the determination of trigonometric parallaxes. It seemed wise that photographic work with the refractor should be started, and accordingly a With only four telescopes devoted to the determination of stellar distances of Stellar Parallax made with the Yerkes Refractor, and published in the Schlesinger's work on stellar parallax at Yerkes was dis- continued there With the new 40-inch refractor he was able to measure thousands of George Ellery Hale continued his own research on the sun at Yerkes with the pioneered the photographic determination of stellar parallax, increasing a factor of 10 the accuracy of distance measurements over those made visual observations.

The modern method of getting stellar parallaxes, the relative parallax, that is, of two The other predicted effect, stellar parallaxes, had to wait for their discovery until 1838, became the dominant design of all major post-17th century refractors.
