1932- . US physicist who as an elementary
particle physicist at Harvard, has made major
contributions to our understanding of quarks.
In 1964 he proposed the existence of a fourth
`charmed' quark, and later argued that quarks
must be coloured. Insights gained from these
theoret- ical studies enabled Glashow to
consider ways in which some of the
fundamental forces of nature (the weak and
the electromagnetic) could be unified as a
single force now called electroweak force.
For this work he shared the Nobel Prize for
Physics with Abdus Salem and Steven Weinberg.
