Johannes Kepler replaced circles with ellipses in the heliocentric model of the universe.
Aristotle was the first to develop a geocentric theory. But it is generally accepted that the Greek astronomer Ptolemy provided the most elaborated model of the geocentric view of the universe in which the Earth was the center. This idea lasted for centuries until the time of Copernicus.

Copernicus suggested a heliocentric model of the universe. Meaning, the earth was the centre of the universe and other planets had to orbit around the earth. This model of the universe was against Ptolemy's model of a geocentric model; a stationary Earth at the centre of the universe.
Aristarchus of Samos was the first person (that we know of!) that proposed a heliocentric model of the universe, as early as about 200B.C). His model was rejected mainly because of Aristotle's influence.Copernicus was the next person to propose a heliocentric model of the universe which was published in 1547. although very controversial at that time, this model was the one that caught on.

Galileo is famous for observing and proving his heliocentric model of the universe. After his observation the existing model of the universe was slowly phased out.
