TOKYO (AP) _ Akira Yoshizawa, an origami master whose expressive paper gorillas made an art out of Japan's craft tradition, died March 14 of heart failure and pneumonia, his wife said Sunday. He was 94.

Moving far beyond paper cranes and hats, Yoshizawa's origami gorillas appeared ready to lumber through the jungle and his frogs looked like they were on the verge of leaping off their lily pads. His international success gave origami a new respectability in Japan.

``At first, people only thought of origami as entertainment for children,'' said his wife of 45 years, Kiyo Yoshizawa. ``Gradually, it won acceptance.''

Yoshizawa died on March 14 _ the same day of his birth in 1911 _ after spending close to two months in the hospital, said Kiyo Yoshizawa.

His first encounter with origami came at the age of 3 when a neighbor folded him a boat, but Yoshizawa only began intently studying paper folding to explain tasks to younger colleagues at the ironworks factory where he worked during World War II.

After the war, Yoshizawa poured his energy into origami while supporting himself with odd jobs. In the 1950s, his expressive figures captured the interest of Gershon Legman, the U.S. anthropologist who helped exhibit his work at the Stedelijk Museum in Amsterdam.

In the decades after, Yoshizawa traveled to countries from France to Indonesia to Peru to the United States, popularizing origami.

He liked to say that origami served as a ``common language'' for the world.

``A few folding techniques and a little inspiration are all you need to recreate the wonders of nature from a single sheet of paper,'' he wrote in one of his origami guides.

Keiko Suda, a curator at the Komagane Kogen Art Museum where Yoshizawa taught each summer from 2001 to 2003, said Yoshizawa told students they needed to be keen observers before they created.

``He told one child that if he wanted to fold a firefly, he must observe fireflies first,'' Suda said. ``He himself would research and study before he did origami and taught the children to do the same.''
