Leonardo was born in the town of Vinci, Italy on April 15th 1452. Not much is known about his childhood except his father was wealthy and famous and had a number of wives - Once he reached the age of 14 he became an apprentice of the famous Artist Verrocchio, this is when he learned about art, drawing, painting, sculpture and architecture.

Assistant at Verrocchio's Workshop
Once Leonardo's Apprenticeship had came to an end, became Verrocchio's Assistant at Verrocchio's Workshop - His earliest painting came to be in Verrocchio's Baptism of Christ in 1475, Leonardo executed two of the Angels and as well as the distant landscape and added the final touches to Christ' figure, determining the texture of the flesh.
Independent Master
Leonardo had finally mastered in all areas of art and even mastered engineering, about 1478 he had set up his own Studio, in 1481 he received a major church commission for an altarpiece, the Adoration of the Magi. In unfinished painting. Leonardo's new approach is far more developed. A crowd of spectators, with varied faces, looks at the main group of the Virgin and Child. There is a strong sense of continuing movement. Leonardo placed the Virgin and Child in the center. Traditionally in paintings of this theme they had appeared at one side of the picture, approached by the Kings from the other side.

The  Magi alterpiece was left unfinished because Leonardo left Florence in 1482 to accept the post of court artist to the Duke of Milan. In leaving, Leonardo followed a trend set by masters of the older generation who went to Venice and Rome to execute commissions larger than any available in their native Florence.
Milan
Leonardo presented himself to the Duke of Milan as skilled in many crafts, but particularly in military engineering. He also produced remarkable machinery for stage set-ups. Both activities point to his intense interest in the laws of motion and propulsion (the movement or push forward), a further aspect of his interest in things and their workings.

Leonardo's first Milanese painting is the altarpiece  Virgin of the Rocks. It makes use of a respected tradition in which the Holy Family is shown in a cave. This setting becomes a vehicle for Leonardo's interests in representing nature in dimmed light, which blends together the outlines of separate objects. He once commented that artists should practice drawing at dusk in courtyards with walls painted black.
The other surviving painting of Leonardo's Milanese years is the  Last Supper (1495–1497). Instead of using fresco (painting on fresh plaster with special water color paints), the traditional medium for this theme, Leonardo experimented with an oil-based medium, because painting in true fresco makes areas of color appear quite distinct. Unfortunately, his experiment was
unsuccessful. The paint did not stick well to the wall, and within fifty years the scene was reduced to a confused series of spots. What exists today is largely a later reconstruction.
When the Duke of Milan was overthrown by the French invasion in 1499, Leonardo left Milan. He visited Venice briefly, where the Senate consulted him on military projects, and traveled to Mantua.
Florence(1500-1506)
In 1500 Leonardo returned to Florence, where he was received as a great man. Florentine painters of the generation immediately following Leonardo were excited by his modern methods, with which they were familiar through the unfinished  Adoration of the Magi. Leonardo had a powerful effect on the younger group of artists.
Leonardo even served a term as military engineer for Cesare Borgia in 1502, and he completed more projects during his time in Florence than in any other period of his life. In his works of these years, the concentration is mostly on portraying human vitality, as in the  Mona Lisa. It is a portrait of a Florentine citizen's young third wife, whose smile is called mysterious because it is in the process of either appearing or disappearing.
Leonardo's great project (begun 1503) was a cavalry battle scene that the city commissioned to adorn the newly built Council Hall of the Palazzo Vecchio. The work is only known today through some rapid rough sketches of the groups of horsemen, careful drawings of single heads of men, and copies of the entire composition. Leonardo began to paint the scene but was called back to Milan before the work was completed. A short time thereafter, the room was remodeled and the fragment was destroyed.
Milan(1506-1513)
Leonardo was called to Milan in 1506 by the French governor in charge to work on an equestrian statue (a sculpture of a leader riding a horse) project, but he produced no new paintings. Instead he turned more and more to scientific observation. Most of Leonardo's scientific concerns were fairly direct extensions of his interests as a painter, and his research in anatomy (the structure of a living organism) was the most fully developed. Early Renaissance painters had attempted to render the human anatomy with accuracy. Leonardo went far beyond any of them, producing the earliest anatomical drawings still followed today.
Leonardo filled notebooks with data and drawings that reveal his other scientific interests: firearms, the action of water, the flight of birds (leading to designs for human flight), the growth of plants, and geology (the study of earth and its history). Leonardo's interests were not universal, however. Theology (the study of religion), history, and literature did not appeal to him. All his interests were concerned with the processes of action, movement, pressure, and growth. It has been said that his drawings of the human body are less about how bodies are and more about how they work.
Last years
In 1513 Leonardo went to Rome, where he remained until 1516. He was much honored, but he was relatively inactive and remarkably aloof (apart) from its rich social and artistic life. He continued to fill his notebooks with scientific entries.
The French king, Francis I (1494–1547), invited Leonardo to his court at Fontainebleau, gave him the title of first painter, architect, and mechanic to the king, and provided him with a country house at Cloux. Leonardo was revered for his knowledge more than for any work he produced in France. He died on May 2, 1519, at Cloux.
