Arthur Schawlow attends Vaughan Road Collegiate Institute (now Vaughan Road Academy). He is very interested in electrics, mechnics and astronomy and reads a lot about it in the library.

Arthur Schawlow returns to University and studies optical spectroscopy under M.F. Crawford and H.L. Welsh. He earns his Ph.D. in 1949.

Arthur Schawlow joins Stanford University and remains there till his retirement in 1991. He is appointed Professor of Physics in 1978.

Arthur Schawlow dies in Palo Alto in April 1999.

Because of the economic depression Arthur Schawlow cannot study engeneering but he wins a scholarship which enables him to enters the University of Toronto to study physics and mathematics. He graduates in 1941.

Arthur Schawlow and Nicolaas Bloembergen are awarded the Nobel Prize in Physics in 1981 for their contribution to the development of laser spectroscopy. They share the prize with Kai M. Siegbahn.

Arthur Schawlow marries Aurelia Townes, the sister of Charles H. Townes. They have three children.

Canada enters the second world war and Arthur Schawlow is drafted into the army. He teaches classes to armed service personnel at the University of Toronto. From 1944 till 1945 he works at a radar factory.

Arthur Schawlow works as a physicist at Bell Telephone Laboratories (now Bell Laboratories). There his research is mostly on superconductivity and nuclear quadrupole resonance. Schawlow continues to colaborate with C.H. Townes and they work on the principles of the maser to much shorter wavelenghts to make an optical maser (now laser). He begins work on optical properties and spectra of solids.

Arthur Leonard Schawlow is born in Mount Vernon, New York to Helen (née Mason) and Arthur Schawlow in 1921. The family moves to Toronto, Canada in 1924.

Arthur Schawlow obtains a postdoctoral fellowship and attends Columbia University. There he works with Charles H. Townes on microwave spectroscopy.
