M. A. B. Beg

A memorial was published in his memory (widely known as The "M.A.B. Beg Memorial Volume") in 1991 by World Scientific, which includes several papers written by him as well as other prominent particle physicists.

He died peacefully at his home in Manhattan, New York, on 30 January 1990, survived by his wife Nancie. An obituary was published in New York Times on 1 February 1990.

He joined the faculty of physics at the Rockefeller University in 1964 and was promoted to full Professor in 1968. Soon after his appointment, beginning with 1965 he became a consultant at the Brookhaven National Laboratory (serving on its High Energy Advisory Committee from 1975 to 1978, which took decisions on the selection of experiments to be conducted at the laboratory.) He also contributed significantly to other global particle physics endeavors, most notably, at the Stanford Linear Accelerator Center and at the European Organization for Nuclear Research. He was appointed as a fellow of the American Physical Society and the New York Academy of Sciences, in addition to recognition by the American Institute of Physics.

Before moving to England, Bég's early work was focused toward nuclear physics, and got interested in theoretical physics after accepting his postdoctoral fellowship (1958-1960) at the University of Birmingham, working under Sir Rudolf Peierls at the department of physics, followed by his second post-doc at the Brookhaven National Laboratory at Upton, New York. His work at BNL earned him a membership at the Institute for Advanced Study in Princeton, New Jersey (1962–64), where he spent two highly-productive years in developing the foundations of valuable work he later carried out.

Mirza Abdul Baqi Bég (20 September 1934 – 30 January 1990), also known as MAB Bég or Baqi Bég, was a Pakistan theoretical physicist and a professor of physics at the Rockefeller University whose contributions were vital in string theory and particle physics. He is credited mainly with his role in laying down the theoretical foundations of the quark theory as well as development of the SU(6) model.

Bég was born in Etawah, Uttar Pradesh in India on 20 September 1934. Following the partition of India in 1947, his family migrated to Pakistan, only to be settled in Karachi, Sindh, Pakistan. After finishing school in Karachi, Bég went to attend the University of Sindh in Hyderabad, graduated with BSc with honors in Physics in 1951. Upon returning to Karachi, Bég attended the Karachi University where he graduated with his MSc in Mathematics with area focused on the applied application in 1954. Bég went to United States for his doctoral studies, attending the University of Pittsburgh, where he was conferred with PhD in nuclear physics under Dr. Philip M. Stehl in 1958.
