Ernest Marsden

Ernest Marsden was a British physicist known for his work in atomic physics during the early 20th century. He played a key role in the famous Geiger-Marsden experiment, conducted with Hans Geiger and Ernest Rutherford, which involved firing alpha particles at thin gold foil to study atomic structure. This experiment led to the discovery of the atomic nucleus, transforming our understanding of atoms. Marsden’s contributions helped establish the modern model of the atom, and he later held prominent scientific positions, promoting research and education in physics.
