  Sir Joseph John Thomson
Thomson was the son of a bookseller in a suburb of Manchester.
Thomson's conclusion that the corpuscles were present in all kinds of matter was strengthened during the next three years, when he found that corpuscles with the same properties could be produced in other ways--e.g., from hot metals.
Thomson may be described as "the man who split the atom" for the first time, although "chipped" might be a better word, in view of the size and number of electrons.

Thomson may be described as "the man who split the atom" for the first time, although "chipped" might be a better word, in view of the size and number of electrons.
Thomson was, moreover, an outstanding teacher; his importance in physics depended almost as much on the work he inspired in others as on that which he did himself.

Thomson was one of the founders of modern physics.
In addition to his own research, Thomson made a significant contribution during his long tenure as director of the Cavendish Laboratory in making it a leading center for atomic research where many important developments in modern physics occurred.
He was knighted (1908), served (1915–20) as president of the Royal Society, and was master of Trinity College, Cambridge, from 1918 until his death.

Sir Joseph John Thomson was born in Cheetham Hill, a suburb of Manchester on December 18, 1856.
Thomson's early interest in atomic structure was reflected in his Treatise on the Motion of Vortex Rings which won him the Adams Prize in 1884.
Thomson co-operated with Professor J. Poynting in a four-volume textbook of physics, Properties of Matter and in 1895 he produced Elements of the Mathematical Theory of Electricity and Magnetism, the 5th edition of which appeared in 1921.

Sir Joseph John Thomson (1856-1940) played a pivotal role in developing our understanding of the electron.
Thomson showed that with the application of both electric and magnetic fields, he could balance the deflections and obtain a straight beam.
From the perception of solid matter, it was presumed that this positive residual matter filled the entire space of the atom, giving rise to what has been called the "Thomson model" of the atom.

Thomson began his studies of the properties of "cathode rays" in 1894 and proved in 1895 that they carried a negative charge.
Thomson had thus opened the door to the world of isotopes and had provided a beginning for the method of analysis now known as mass spectrography.
Thomson's Recollections and Reflections (1936) is one of the notable scientific autobiographies.

Thomson’s discovery was based on the theory that a cathode ray particle is more than one thousand times lighter than the lightest chemical atom and a universal constituent of matter.

Thomson demonstrated (1897) that cathode rays were actually units of electrical current made up of negatively charged particles of subatomic size.
He believed them to be an integral part of all matter and theorized a model of atomic structure in which a quantity of negatively charged electrons was embedded in a sphere of positive electricity, the two charges neutralizing each other.
Thomson was a highly gifted teacher--seven of his research assistants as well as his son, George, won Nobel Prizes for physics--and he led Great Britain to dominance in the field of subatomic particles in the early decades of the 20th century.

Thomson suspected that traces of gas remaining in the tube were being turned into an electrical conductor by the cathode rays themselves.
Thomson announced the hypothesis that "we have in the cathode rays matter in a new state, a state in which the subdivision of matter is very much further than in the ordinary gaseous state: a state in which all matter...
Thomson proposed a model, sometimes called the 'plum pudding' model, in which thousands of tiny, negatively charged 'corpuscles' swarm inside a sort of cloud of mass less positive charge.

Sir James Dewar kindly supplied me with some gases obtained from he residues of liquid air; the first sample had been treated so as to contain the heavier constituents.
The positive-ray photograph gave the lines of xenon, krypton, argon, and a faint line due to neon; there were no lines on the photograph unaccounted for, and so we may conclude that there are no heavy unknown gases in the atmosphere occurring in quantities comparable with that of xenon.
The second sample from Sir James Dewar contained the lighter gases; the photograph shows that, in addition to helium and neon, there is another gas with an atomic weight about 22.

Thomson interpreted the deflection of the rays by electrically charged plates and magnets as evidence of "bodies much smaller than atoms" that he calculated as having a very large value for the charge to mass ratio.
Thomson's seminal work, The Seasons (1726-30, revised 1744), is a laboured and uneasy epic poem, yet it is considered to be the first substantial poem in English to have Nature, or, perhaps, the landscape, as its main subject.
Thomson is, properly, credited by historians of the Picturesque, with occupying a position analogous to that of Claude or Poussin in painting.
