HEBRON, Ind. (AP) _ The Rev. Juan S. Boonstra, voice of the Spanish-language broadcasts of the Christian Reformed Church, died Thursday. He was 69.

Boonstra's program, ``The Back to God Hour,'' began 26 years ago. At his death, the broadcast was carried by almost 400 radio stations in South and Central America.

A native of Tres Arroyos, Argentina, Boonstra graduated in 1954 from Calvin Seminary in Grand Rapids, Mich. His first posting as a pastor was in a small church in his native country, where his parishioners were scattered over hundreds of miles. He began using radio to reach a wider audience in 1969.

Boonstra is survived by his wife, Natalie, three sons, one daughter and 13 grandchildren.

Joseph Needham

CAMBRIDGE, England (AP) _ Joseph Needham, scientist, scholar and renowned authority on China, died Friday at age 94.

The death was announced by the Rev. John Sturdy, dean of Gonville and Caius, the Cambridge University college with which Needham was associated for 70 years.

Noel Joseph Terence Montgomery Needham was born Dec. 9, 1900. He was a devout Anglican as well as a Marxist and admirer of Mao Tse-Tung.

He trained as an embryologist and his 1934 ``History of Embryology'' has been described as the standard work on the subject.

He became interested in China in the late 1930s under the influence of scientist Gwei-Djen Lu, a student of his first wife, eminent biochemist Dr. Dorothy Needham. She died in 1987 and he married Gwei-Djen Lu-Needham in 1989. She died in 1991.

Needham began writing about China in 1946. In 1949 he launched his greatest work, a seven-volume series, ``Science and Civilization in China.''

In 1976, Needham became director of the Needham Research Institute in Cambridge, where specialists continue to study the impact of China on the world.
