Florentine physician, philosopher and botanist Andrea Cesalpino was born #OTD in 1524.
"De Plantis Libri XVI" (1583), is one of the earliest systematic treatises on plants. This book laid the groundwork for modern botanical classification. He organized plants based on their fruits and seeds rather than their medicinal properties, which was the common practice at the time. This method was a precursor to the binomial nomenclature system later developed by Carl Linnaeus.
