David Hume Kennerly shot candid portraits of President Gerald Ford and won a Pulitzer Prize for his remarkable images of the Vietnam War.

Bruce Dale had more than 2,000 pictures published in National Geographic magazine during a career that sent him to 75-plus countries, shooting high in the sky, under the water and spots in between.

Both will be in Lawrence this week to give talks about their work at the Lawrence Arts Center. The appearances are sponsored by the Lawrence Journal-World.

Kennerly, who published his first photograph at age 15 in his high school newspaper in Roseburg, Ore., is a contributing editor for Newsweek magazine and NBC news. His first official photography jobs – as staff photographer for the Oregon Journal and then the Portland Oregonian – led him to a position with United Press International.

That gig landed Kennerly in Vietnam, where he snapped some of the most indelible images of the war to appear in U.S. media. The Pulitzer came in 1972.

He next worked for LIFE and Time magazines, concentrating on Washington politics. He shot one among the dozens of his images that have helped define American photojournalism on the South Lawn of the White House, after Richard Nixon resigned. Kennerly was there when Nixon departed, and he captured the historic photo of Nixon’s wave good-bye.

Nixon’s successor, President Gerald Ford, invited Kennerly to be White House Photographer. During his tenure, from 1974 to 1977, Kennerly photographed world leaders including Emperor Hirohito in Japan, Leonid Brezhnev in the USSR, Franco in Spain, Ceausescu in Romania, Marcos in the Philippines, Tito in Yugoslavia, Suharto in Indonesia, Deng Xiao Ping in the People’s Republic of China and Queen Elizabeth during the bicentennial celebration at the White House.

When the Ford presidency ended, Time called the 29-year-old Kennerly back to action, sending him to photograph Fidel Castro in Cuba, President Anwar Sadat in Egypt and the horrors of Jonestown in Guyana, among many other assignments. He went on to major projects for Newsweek, LIFE, ABC Good Morning America Sunday, and George Magazine.

Kennerly has photographed more than 35 covers for Time and Newsweek, covered assignments in more than 130 countries and counts more than one million images in his photographic archive.

Bruce Dale photographed politicians and world leaders, too. In 1989, he was named White House Photographer of the Year.

But he really specialized in everything else.

His work with National Geographic spanned the most complex of scientific, technological and anthropological subjects. One of his more memorable photos involved mounting two cameras on the tail of a Lockheed TriStar jumbo jet to make spectacular views of the big jet in flight. One, a 23-second time exposure, led to a three-page gatefold in Geographic – the other a cover on the magazine.

Dale’s photos range from sensitive people studies, such as his books on Gypsies and American Mountain People, to highly technical work, such as working with pulsed laser photography to help produce a hologram of an exploding crystal ball for the Geographic’s 100th Anniversary cover.

His vision and creativity twice earned him the title Magazine Photographer of the Year, and his innovative work with digital imaging brought him honors from the Smithsonian Institution. In addition to many other awards, one of his photographs now journeys beyond the solar system on board NASA’s Voyager Spacecraft, as testimony about planet Earth.

Dale left National Geographic to pursue a blend of editorial and corporate and advertising photography. His book, “The American Southwest,” was published in 1999 by National Geographic.
