Walter Marvin Koenig is an American actor, writer, teacher, and director, known for his roles as Pavel Chekov in Star Trek and Alfred Bester in Babylon 5.
Koenig played Ensign Pavel Chekov, navigator on the USS Enterprise, in the original Star Trek television series (starting in Season 2) and in all of the movies featuring the original cast (including Star Trek Generations). Show creator Gene Roddenberry hoped that Koenig would increase the show’s appeal to young people. After Chekov, Koenig had a starring role as Psi Cop Alfred Bester on the television series Babylon 5. Koenig was the “Special Guest Star” in twelve episodes and, at the end of the third season, the production company applied for an Emmy nomination on his behalf.
In 2007, Koenig was asked by the human rights group U.S. Campaign for Burma to help in their grassroots campaign about the humanitarian crisis in Burma. As detailed on his official website, he visited refugee camps along the Burma-Thailand border from July 16 to July 25, 2007.
