Margaret Lockwood, 73, one of the most popular British actresses of the 1940s, whose first prominent role was as the frightened heroine in Alfred Hitchcock's 1938 movie "The Lady Vanishes," died July 15 in London. The cause of death was not reported.

Her other film credits included "Night Train" (1940), "The Stars Look Down" (1941), "The Man in Gray" (1943), "The Wicked Lady" (1945) and "Trent's Last Case" (1954). She appeared in more than 40 movies. Her last appearance was a 1976 cameo role in "The Slipper and the Rose."

TROY DIXON

Rap Dancer

Troy Dixon, 22, a dancer for the rap group Heavy D & the Boyz, whose stage name was Trouble T-Roy, died July 15 at a hospital in Indianapolis. He died from injuries he received after falling 30 feet during horseplay at an arena, authorities said.

Police said he was standing on the third-level ramp at the Market Square Arena late Saturday when another group member, while fooling around, rolled a trash barrel down the ramp toward him. Mr. Dixon jumped on a four-foot retaining wall to avoid the barrel and fell over backward to the ground, police said.

The group, from Mount Vernon, N.Y., was on a 10-city tour and was one of the headline acts for Black Expo, which also featured the rap group Public Enemy. Heavy D & the Boyz won a Soul Train Music Award and an NAACP Image Award for the album "Big Tyme."

RALPH HUMPHREY

Painter

Ralph Humphrey, 58, a painter whose works linked abstract expressionism and minimalism, died July 14 at a hospital in New York City. He had emphysema and congestive heart failure.

He moved to New York in 1956, when abstract expressionism was at its height, and became one of the painters and sculptors who set the pattern for American art of the 1960s and 1970s.

Mr. Humphrey taught painting at Hunter College in New York. His work is represented in the collections of the Museum of Modern Art and the Whitney Museum of American Art.
