After earning his MD from the Albert Einstein College of Medicine in New York City, Erol Onel went on to become the director of medical affairs at Ferring Pharmaceuticals in Suffern, New York. Erol Onel also plays the violin.
While the first violins (called fiddle in some quarters) were an evolution of handheld stringed instruments that were played in Europe during the middle ages, experts suspect that these devices sprung from models developed in Central Asia, like the Mongolian morin khuur.
Nevertheless, the first recognizable violins are considered to have emerged in northern Italy during the 16th century. Though three string versions had been circulating since earlier in the century, a luthier named Andrea Amati built the first four string model in 1555.
The instrument was so well received by both musicians and the nobility that in 1560, King Charles IX of France ordered 24 of them. One of this set still exists and is the oldest violin in the world.
