Engineer Builds Baby Walker (Sep, 1939)
Engineer Builds Baby Walker
To teach his young son to walk, a Swiss engineer built the curious apparatus shown above. Pairs of wooden arms are strapped at one end to the infant’s legs and at the other to the legs of an adult, so that the latter can control the baby’s leg movements. A harness connected to a pulley on an overhead wire holds the child upright while it is taking its first steps.
