Nicholaus Copernicus

Astronomer Nicolaus Copernicus Was instrumental in establishing the concept of a heliocentric solar system, in which the sun, rather than the earth, is the center of the solar system.

 German: Nikolaus Kopernikus; 19 February 1473 – 24 May 1543) was a Renaissance mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at the center of the universe, likely independently of Aristarchus of Samos, who had formulated such a model some eighteen centuries earlier.^[a]

The publication of Copernicus' model in his book De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), just before his death in 1543, was a major event in the history of science, triggering the Copernican Revolution and making an important contribution to the Scientific Revolution

Sir Francis Bacon's greatest contribution was developing the Baconian method, also known as empiricism and the scientific method. Coupled with his belief that knowledge and science are to be used for the relief of humanity's misery, his influence led to astounding progress of the Industrial Age

Novum Organum (New Method) The Novum Organum is a philosophical work by Francis Bacon published in 1620. The title is a reference to Aristotle's work Organon, which was his treatise on logic and syllogism, and is the second part of his Instauration

Isaac Newton 

Sir Isaac Newton PRS was an English mathematician, astronomer, and physicist who is widely recognised as one of the most influential scientists of all time and a key figure in the scientific revolution

Isaac Newton was born on Christmas Day, 1642, at Woolsthorpe, a hamlet in southwestern Lincolnshire. In his early years Lincolnshire was a battle-ground of the civil wars, in which the challenging of authority in government and religion was dividing England's population. Also of significance for his early development were circumstances within his family. He was born after the death of his father, and in his third year his mother married the rector of a neighboring parish, leaving Isaac at Woolsthorpe in the care of his grandmother.

William Harvey was an English physician who made seminal contributions in anatomy and physiology.

William Harvey (1 April 1578 – 3 June 1657) was an English physician who made seminal contributions in anatomy and physiology. He was the first known physician to describe completely and in detail the systemic circulation and properties of blood being pumped to the brain and body by the heart, though earlier writers, such as Realdo Colombo, Michael Servetus, and Jacques Dubois, had provided precursors of the theory.^[1][2] In 1973 the William Harvey Hospital was constructed in the town of Ashford, several miles from his birthplace of Folkestone

William's father, Thomas Harvey, was a jurat of Folkestone where he served the office of mayor in 1600. Records and personal descriptions delineate him as an overall calm, diligent, and intelligent man whose "sons... revered,
