Jerónimo de Ayanz y Beaumont, a Renaissance polymath overshadowed by history, was not only a distinguished soldier and politician but also a prolific inventor whose contributions went largely unnoticed. His adventurous military exploits, including legendary feats in battles, earned him royal honors and acclaim from contemporaries like Lope de Vega.
However, it was his groundbreaking inventions, such as the diving suit and steam engine, that truly distinguished him as Europe's greatest inventor of his time. Despite his remarkable achievements, Ayanz's legacy remained relatively obscure until recent times.
