Leonardo Bruni or Leonardo Aretino was an Italian humanist, historian and statesman, often recognized as the most important humanist historian of the early Renaissance. He has been called the first modern historian. He was the earliest person to write using the three-period view of history: Antiquity, Middle Ages, and Modern. The dates Bruni used to define the periods are not exactly what modern historians use today, but he laid the conceptual groundwork for a tripartite division of history.
Leonardo di ser Piero da Vinci was an Italian polymath of the High Renaissance who was active as a painter, draughtsman, engineer, scientist, theorist, sculptor, and architect. While his fame initially rested on his achievements as a painter, he also became known for his notebooks, in which he made drawings and notes on a variety of subjects, including anatomy, astronomy, botany, cartography, painting, and paleontology. Leonardo is widely regarded to have been a genius who epitomized the Renaissance humanist ideal, and his collective works comprise a contribution to later generations of artists matched only by that of his younger contemporary, Michelangelo.

Leonhard Frank was a German expressionist writer. He studied painting and graphic art in Munich, and gained acclaim with his first novel The Robber Band. When a Berlin journalist celebrated in a famous café about news of the loss of the ship RMS Lusitania, torpedoed by a German submarine, Frank was upset – and slapped the man in his face. That is why he went into exile in Switzerland (1915–18), where he wrote a series of pacifist short-stories published under the title Man is Good. He returned to Germany, but after the Nazis gained power in 1933 Frank had to emigrate a second time. He lived in Switzerland again, moved to London, then Paris and finally fled under adventurous conditions to the United States in 1940, returning to Munich in 1950. His best-known novels were In the Last Coach and Carl and Anna, which he dramatized in 1929. In 1947 MGM made a movie titled Desire Me out of this story.
