Paul Vathis, 77, whose 56 years as an Associated Press photographer included a 1962 Pulitzer Prize for his picture of President Kennedy and former President Dwight D. Eisenhower walking together at Camp David after the Bay of Pigs invasion, died Tuesday in his sleep in Harrisburg, Pa.

From the AP bureau in Harrisburg, where he spent most of his career, Mr. Vathis built a national reputation for his skill with a lens, his instinct for news and his boundless energy. In addition to his prize-winning shot of Mr. Kennedy and Mr. Eisenhower, Mr. Vathis provided the only newspaper photos of Wilt Chamberlain's history-making 100-point basketball game in 1962.

Arvell Shaw, 79, a bassist who played with Louis Armstrong longer than any other musician and was the last surviving member of the trumpeter's small combo, the Original All Stars, died Dec. 5 in New York.

Mr. Shaw joined the Louis Armstrong Orchestra in 1945 at age 22. He was one of the few musicians Mr. Armstrong kept on when he disbanded the orchestra in 1947 to form the smaller All Stars. Mr. Shaw played intermittently with the group until Mr. Armstrong's death in 1971.

Like many bass players of his era, Mr. Shaw preferred to stay in the background, providing the anchor for Mr. Armstrong's songs. He appeared in several movies with Mr. Armstrong, most notably 1954's The Glenn Miller Story and 1956's High Society.
