Optical telescope
The telescope is more a discovery of optical craftsmen than an invention of a scientist. The lens and the properties of refracting and reflecting light had been known since antiquity and theory on how they worked were developed by ancient Greek philosophers, preserved and expanded on in the medieval Islamic world, and had reached a significantly advanced state by the time of the telescope's invention in early modern Europe. But the most significant step cited in the invention of the telescope was the development of lens manufacture for spectacles, first in Venice and Florence in the thirteenth century, and later in the spectacle making centers in both the Netherlands and Germany. It is in the Netherlands in 1608 where the first recorded optical telescopes (refracting telescopes) appeared. The invention is credited to the spectacle makers Hans Lippershey and Zacharias Janssen in Middelburg, and the instrument-maker and optician Jacob Metius of Alkmaar.
The Telescope
The Telescope was a magazine for amateur astronomers published between 1931 and 1941. The magazine was first published as a quarterly under the editorship of Harlan Stetson, director of the Perkins Observatory in Ohio. It featured popular articles about contemporary research. In 1934 Stetson moved to Cambridge, Massachusetts and brought the magazine with him. Publishing duties were assumed jointly by the Harvard College Observatory and the Bond Astronomical Club, under the editorship of Donald H. Menzel. "The Telescope" became a bimonthly publication at this time.
