The Schneider Grunau Baby (named for the town where Schneider's factory was located - now Jesow in Poland) was a single-seat sailplane first built in Germany in 1931, and with some 6,000 examples constructed in some 20 countries, is the most widely-built sailplane to date. It was relatively easy to build from plans, it flew well, and the aircraft was strong enough to handle mild aerobatics and the occasional hard landing. When the Baby first appeared, it was accepted wisdom that the pilot should feel as much unimpeded airflow as possible, the better to sense rising and falling currents of air, temperature changes and the like.
It was designed by Edmund Schneider as a smaller version of his ESG 31 of the previous year, incorporating a new elliptical wing design based on work done by Akaflieg Darmstadt. The intention was to create an aircraft suitable both for training and for cross-country soaring.
Typical for its day, it was a high-wing braced monoplane with a fuselage of hexagonal cross-section and an open cockpit. The Baby was an instant success, and was enthusiastically promoted by gliding champion Wolf Hirth. An extensive redesign followed in 1932 following the fatal crash of an unrelated Schneider design, resulting in the Baby II. This version and the definitive Baby IIb that followed it were adopted as a standard sailplane trainer for the Deutsche Luftsport Verband (later the Nationalsozialistiche Fliegerkorps).
Following World War II, the Baby was built in France (as the Nord 1300) and the United Kingdom (as the Elliotts Baby EoN and the Slingsby T5 - Slingsby also used it as the basis for a number of their own designs). Edmund Schneider emigrated to Australia, where he continued development of the aircraft into the Baby 3 and Baby 4, which had enclosed cockpits.
