Who came up with the idea that newborn babies are delivered by the stork?

The ancient Scandinavians appear to be responsible for the legend of newborn babies being delivered by the stork.

The myth grew out of observations of storks, their nesting in chimneys, their monogamy, and their gentle behavior toward their kin.

The myth did not gain worldwide acceptance until the nineteenth century, when Danish writer Hans Christian Andersen popularized it in his fairy tales.
