Gas laser pioneeer William R. Bennett dies

William R. Bennett Jr., a physicist and inventor who helped develop a gas laser in the 1960s in technology that later revolutionized surgery and made possible compact-disc players and grocery-store scanners, died on June 29 at his home in Haverford, Pa. He was 78.

In the late 1950s, while working at Bell Laboratories in Murray Hill, N.J., Dr. Bennett and a small scientific team assembled a gas laser, the first of its kind able to send out a continuous beam of red light.
