List of Famous people named Christiaan

Christiaan Neethling Barnard was a South African cardiac surgeon who performed the world's first human-to-human heart transplant operation. On 3 December 1967, Barnard transplanted the heart of accident-victim Denise Darvall into the chest of 54-year-old Louis Washkansky, with Washkansky regaining full consciousness and being able to easily talk with his wife, before dying 18 days later of pneumonia, largely brought on by the anti-rejection drugs that suppressed his immune system. Barnard had told Mr. and Mrs. Washkansky that the operation had an 80% chance of success, an assessment which has been criticised as misleading. Barnard's second transplant patient, Philip Blaiberg, whose operation was performed at the beginning of 1968, lived for a year and a half and was able to go home from the hospital.

Christiaan Huygens, also spelled Huyghens, was a Dutch physicist, mathematician, astronomer and inventor, who is widely regarded as one of the greatest scientists of all time and a major figure in the scientific revolution. In physics, Huygens made groundbreaking contributions in optics and mechanics, while as an astronomer he is chiefly known for his studies of the rings of Saturn and the discovery of its moon Titan. As an inventor, he improved the design of the telescope with the invention of the Huygenian eyepiece. His most famous invention, however, was the pendulum clock in 1656, which was a breakthrough in timekeeping and became the most accurate timekeeper for almost 300 years. Huygens was an outstanding mathematician and, because he was the first scientist of the modern era to transfer mathematical inquiry to describe unobservable physical phenomena, he has been called the first theoretical physicist and the founder of modern mathematical physics.
