Ludwik Gross

Cancer Researcher

Ludwik Gross, 94, whose cancer research showing that viruses could cause cancer in animals resulted in his winning the immensely prestigious Albert and Mary Lasker Foundation prize in 1974, died July 19 in New York. The cause of death was not reported.

The Lasker jury said his findings opened the field of tumor virology in mammals and laid the groundwork for later discoveries of cancer-inducing viruses in other species.

A medical journalist, Dr. Gross was a member of the National Academy of Sciences and wrote "Oncogenic Viruses," a textbook that became a standard in the field.

His last article appeared in 1998 in the publication Proceedings.

Mr. Diaz won international acclaim with his 1947 story collection, "Terrazo," (Terrace). Many of his stories are required reading in Puerto Rican schools, and "Terrazo" has been translated into 10 languages.

In the most famous tale, "El Josco" (The Swarthy One), two neighbors pit a Puerto Rican bull against an American bull in a fight. The showdown dramatized the U.S. territory's often painful relationship with the United States.
