In the first program of direct photography with the 72-inch telescope of the Dominion Astrophysical Observatory, 1931–1934, the compact and distant globular cluster NGC 6934 in Delphinus was searched for variables for the first time by HSH. The 51 discovered were published in 1938 (Sawyer-Hogg 1938). From 1935 to 1964 the observational program was continued with the 74-inch telescope of the David Dunlap Observatory and a total of 161 plates was accumulated. In addition, six Mount Wilson plates from 1911 to 1917 were available to us.
