A. Winnecke published a series of observations, entitled "Doppelsternmessungen" (Double Star Measurements), in Astronomische Nachrichten No. 1738, vol 73, p 147-160, published in Altona, February 8, 1869.. Within this paper, he reports of numerous observational results, obtained with various refractors from Bonn, Berlin, and Pulkovo. Besides reporting observations of wellknown pairs, he includes a list of seven "new" double stars, marked as "Nova" (latin for New; p 156 of the paper). He notes that he later found that three of them (30 Eri, Bradley 757, and 44 Cyg) had been recognized as double stars earlier by Peters and Alvan Clarke.
