Engineer

Leonardo di ser Piero da Vinci

(pronunciation , April 15, 1452 – May 2, 1519) was an Italian polymath, having been a scientist, mathematician, engineer, inventor, anatomist, painter, sculptor, architect, botanist, musician and writer. Born as the illegitimate son of a notary, Piero da Vinci, and a peasant woman, Caterina, at Vinci in the region of Florence, Leonardo was educated in the studio of the renowned Florentine painter, Verrocchio. 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, spending his final years in France at the home given to him by King François I.

Leonardo has often been described as the archetype of the "Renaissance man", a man whose seemingly infinite curiosity was equalled only by his powers of invention.[1] 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.

It is primarily as a painter that Leonardo was and is renowned. Two of his works, the Mona Lisa and The Last Supper, occupy unique positions as the most famous, most reproduced and most parodied portrait and religious painting of all time, their fame approached only by Michelangelo's Creation of Adam.[1] Leonardo's drawing of the Vitruvian Man is also iconic. Perhaps fifteen of his paintings survive, the small number due to his constant, and frequently disastrous, experimentation with new techniques, and his chronic procrastination.[nb 2] 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.

As an engineer, Leonardo's ideas were vastly ahead of his time. He conceptualised a helicopter, a tank, concentrated solar power, a calculator, the double hull and outlined a rudimentary theory of plate tectonics. Relatively few of his designs were constructed or were even feasible during his lifetime,[nb 3] but some of his smaller inventions, such as an automated bobbin winder and a machine for testing the tensile strength of wire, entered the world of manufacturing unheralded.[nb 4] As a scientist, he greatly advanced the state of knowledge in the fields of anatomy, civil engineering, optics, and hydrodynamics.
Biography



Leonardo's earliest known drawing, the Arno Valley, (1473) - UffiziLeonardo was born on April 15, 1452, "at the third hour of the night"[nb 5] in the Tuscan hill town of Vinci, in the lower valley of the Arno River in the territory of Florence.[4] He was the illegitimate son of Messer Piero Fruosino di Antonio da Vinci, a Florentine notary, and Caterina, a peasant[5][3] who may have been a slave from the Middle East.[nb 6][6] Leonardo had no surname in the modern sense, "da Vinci" simply meaning "of Vinci": his full birth name was "Leonardo di ser Piero da Vinci", meaning "Leonardo, son of (Mes)ser Piero from Vinci."[4]

Little is known about Leonardo's early life. He spent his first five years in the hamlet of Anchiano, then lived in the household of his father, grandparents and uncle, Francesco, in the small town of Vinci. His father had married a sixteen-year-old girl named Albiera, who loved Leonardo but died young.[7] In later life, Leonardo only recorded two childhood incidents. One, which he regarded as an omen, was when a kite dropped from the sky and hovered over his cradle, its tail feathers brushing his face.[7] The second occurred while exploring in the mountains. He discovered a cave and was both terrified that some great monster might lurk there, and driven by curiosity to find out what was inside.

Leonard's early life has been the subject of historical conjecture.[8] Vasari, the 16th century biographer of Renaissance painters tells of how a local peasant requested that Ser Piero ask his talented son to paint a picture on a round plaque. Leonardo responded with a painting of snakes spitting fire which was so terrifying that Ser Piero sold it to a Florentine art dealer, who sold it to the Duke of Milan. Meanwhile, having made a profit, Ser Piero bought a plaque decorated with a heart pierced by an arrow, which he gave to the peasant.[9]

The Baptism of Christ (1472–1475)—Uffizi, by Verrocchio and Leonardo
Verrocchio's workshop, 1466–1476
In 1466, at the age of fourteen, Leonardo was apprenticed to one of the most successful artists of his day, Andrea di Cione, known as Verrocchio. Verrocchio's workshop was at the centre of the intellectual currents of Florence, assuring the young Leonardo of an education in the humanities. Other famous painters apprenticed or associated with the workshop include Ghirlandaio, Perugino, Botticelli, and Lorenzo di Credi.[7][10] Leonardo would have been exposed to a vast range of technical skills and had the opportunity to learn drafting, chemistry, metallurgy, metal working, plaster casting, leather working, mechanics and carpentry as well as the artistic skills of drawing, painting, sculpting and modelling.[11][12][13]
