Hero of Alexandria (fl. 2nd century B.C. ), student of Ctesibius, built clockwork into toys. The system he devised to produce toys such as a temple with doors that opened and an altar that lit up while drums and cymbals accompanied dancing figurines and wine and milk poured, is still used today in the design of automatic tea-makers.
