P:Died. Peter Jeffrey Revson, 35, American international road racer; while test driving his Formula I UOP Shadow at the Kyalami circuit near Johannesburg, South Africa. A wealthy playboy--he was recently linked with Marjorie Wallace, the dethroned Miss World titleholder--Revson was more than a dilettante motorist. He was runner-up at the Indianapolis 500 in 1971 and won the British Grand Prix in the same year. His most recent major victories were the British and Canadian Grand Prix in 1973.

P:Died. Anne Klein, 51, trend-setting designer of women's fashions famed for bringing sophistication to casual clothes; of pneumonia following a virus infection; in Manhattan. Petite and canny, Klein rose to prominence by injecting a new elegance into the traditionally cutesie junior-size dresses. She later broadened her scope to include everything from sweaters to shoes.

P:Died. Chet Huntley, 62, for 14 years co-anchor man of NBC'S immensely popular Huntley-Brinkley Report (see THE PRESS).

P:Died. Louis I. Kahn, 73 (TIME, Jan.15,1973), a seminal architect for the past two decades; of a heart attack; in Manhattan. Kahn was a relatively obscure teacher until the early 1950s, when his first major design, the Yale Art Gallery, was constructed. After that, his influence--as seen in the designs of such disciples as Charles Moore and Pop Architect Robert Venturi--became enormous. Kahn was primarily concerned with principles of order and light. His work featured the use of stark, geometric shapes and an emphasis on natural light and the moods created by it. He also incorporated such traditionally concealed "servant" elements as ducts, pipes and storage space into visible design. Slight and white-haired, with a poetic regard for his materials ("A brick is happy when it is an arch"), Kahn was best known for the Salk Institute complex in La Jolla, Calif., and for his recently completed Kimbell Art Museum in Fort Worth. He also designed the capital buildings in Dacca, Bangladesh.

P:Died. Dr. Alan F. Guttmacher, 75, obstetrician and leading apostle of the family-planning movement; of leukemia; in Manhattan. A respected professor and clinician, Guttmacher preached that birth control information and devices must be made available to everyone. In 1962 he became president of Planned Parenthood-World Population and began jetting the globe to spread his message. He urged the use of I.U.D.s in underdeveloped countries, arguing that imperfect contraception was better than none at all.
