Plattes was born around the turn of the seventeenth century. He collapsed in a London street and died – of hunger, according to contemporary reports – in late December 1644. Nothing is known of his background or education, though it has been very speculatively suggested that he came of Dutch stock. It is obvious from his writings that he had an extensive practical knowledge of agriculture, metallurgy and medicine.
