1. Leonardo da Vinci

Leonardo di ser Piero da Vinci [pjero da vint∫i](April 15, 1452 – May 2, 1519) was an Italian polymath, scientist, mathematician, engineer, inventor, anatomist, painter, sculptor, architect, botanist, musician and writer. Leonardo has often been described as the archetype of the Renaissance man, a man whose unquenchable curiosity was equaled only by his powers of invention. He is widely considered to be one of the greatest painters of all time and perhaps the most diversely talented person ever to have lived.

The great Italian, Leonardo da Vinci, was born on April 15, 1452. At an early age he received a decent education but in a small village the opportunities to learn were scarce. His father realisedthat Leonardo had an artist’s gift and in the year of 1469 he sent him to Florence as an apprentice in the in the studio of an artist and sculptor Andrea Verrocchio. Leonardo was left-handed , he behaved in an eccentric way but remembered carefully the teacher’s instructions.

Much of his earlier working life was spent in the service of Ludovico il Moro in Milan. He later worked in Rome, Bologna and Venice and spent his last years in France, at the home awarded him by Francis I.

Leonardo was and is renowned primarily as a painter. Two of his works, the Mona Lisa and The Last Supper, are the most famous, most reproduced and most parodied portrait and religious painting of all time, respectively, their fame approached only by Michelangelo's Creation of Adam. Leonardo's drawing of the Vitruvian Man is also regarded as a cultural icon, being reproduced on everything from the Euro to text books to t-shirts. Perhaps fifteen of his paintings survive, the small number due to his constant, and frequently disastrous, experimentation with new techniques, and his chronic procrastination. Nevertheless, these few works, together with his notebooks, which contain drawings, scientific diagrams, and his thoughts on the nature of painting, comprise a contribution to later generations of artists only rivalled by that of his contemporary, Michelangelo.

Leonardo is revered for his technological ingenuity. He was often busy with the development of military inventions: tanks, flying apparatus, mortar bombs and the construction of fortresses.

He lacked the opportunity to carry out these projects as they were ahead of his time. For instance, tank was used during World War I, almost four hundred years after Leonardo had made a scetch of an armoured car without a horse.

Leonardo developed the sewage system of Milan and advised on the town rebuilding to avoid the threat of plague. Relatively few of his designs were constructed or were even feasible during his lifetime.

As a scientist, he greatly advanced the state of knowledge in the fields of anatomy, civil engineering, optics, and hydrodynamics. He was a pioneer in everything but very often he left his projects unfinished.
