John Thomson
Thomson, Townsend and Wilson are credited for the discovery of electron in 1991.
J.J. Thomson discovered the electron in 1897 while conducting experiments with cathode rays. This discovery was groundbreaking as it provided evidence for the existence of subatomic particles.
His formula allowed other scientists to experiment with their projects.
Marie and Pierre Curie did not discover the atom. John Dalton is credited with the discovery of the atom and J.J. Thomson with the discovery of the electron.
Robert Hooke's discovery of cells in 1665 helped scientists understand the fundamental unit of life and laid the foundation for the field of biology. His work led to the development of the cell theory, which states that all living organisms are composed of cells.

The discovery of iron dates back to ancient times, so there is no specific scientist associated with its discovery. Iron has been used by humans for thousands of years due to its abundance and utility.
The year of the electron discovery is considered 1896.

Thomson, Townsend and Wilson are credited for the discovery of electron in 1991.
Crookes observed that the cathodic rays are deflected by a magnetic field and concluded that this beam is negatively charged. Thomson established that the beam is composed from a new type of particles called by Fitzgerald electrons. But many scientists contributed to the discovery of the electron.

Some key scientists in the historical development of the atom include Democritus (concept of "atomos"), John Dalton (atomic theory), J.J. Thomson (discovery of the electron), Ernest Rutherford (discovery of the nucleus), and Niels Bohr (Bohr model of the atom). Each of these scientists made significant contributions to our understanding of the atom and its structure.
