Dmitri Zaikin, who in March 1960 was chosen with Yuri Gagarin as one of the Soviet Union's first cosmonauts but who never flew into space, died Sunday (Oct. 20) after an extended illness. He was 81.

"The bright memory of Dmitri Zaikin forever remains in the hearts of colleagues, friends, and loved ones," officials at the Yuri Gagarin Cosmonaut Training Center in Star City, Russia, stated in a release on Monday. "Dmitri had a great experience and knowledge of space technology."

Selected among the first 20 Soviet Air Force pilots to train as a cosmonaut, Zaikin was recruited in the same class as Gagarin, who on April 12, 1961 became the world's first person to fly in space. As with his fellow trainees, Zaikin's recruitment was conducted under the veil of secrecy. [10 Best Soviet and Russian Space Missions]

"Initially, they asked if we wanted to become test pilots," Zaikin said in a 1993 interview with researcher Bert Vis. "I said that every pilot dreams about that. Then they asked me, 'and if we asked you to fly into space?' I said I only knew about the first satellite [Sputnik], and [the first dog in space] Laika, and that [Soviet rocket scientist Konstantin] Tsiolkovsky had written about space. They said, 'We want you to be a cosmonaut.'"

Zaikin's status as a cosmonaut wasn't known publicly until 1977, nine years after an exam revealed a stomach ulcer that disqualified him from flying in space, which in turn led to his departure from the space corps a year later in 1969.

"We were asked not to tell anyone about why we had been asked to come," Zaikin told Vis, as reprinted in the 2008 book, "The First Soviet Cosmonaut Team: Their Lives and Legacies" (Springer-Praxis) by Colin Burgess and the late Rex Hall.

"Characterized by humility, [a] high sense of responsibility for his work, hard work, diligence and dedication... he was respected and [had a] well-deserved reputation among his colleagues," read the training center's statement.

With Zaikin's death, only four of former Soviet Union's first 20 cosmonaut trainees are living; Valery Bykovsky, Viktor Gorbatko, Alexei Leonov and Boris Volynov.
