The first baby carriage was invented in 1733 by an English architect named William Kent for the children of the Duke of Devonshire. It consisted of a shell-shaped basket attached to wheels and was set low enough to be pulled by a goat or pony. The first reversible baby carriage that allowed a child to either face toward or away from the person pushing it was invented by William H. Richardson in 1889. His design also improved steering capabilities, but baby carriages remained quite heavy until well into the 20th century. It wasn’t until 1965, when Owen Maclaren began using aircraft aluminum to create lightweight baby carriages, that these perambulators became lighter and easier to manage.
