Abraham L. Pomerantz, 79, a New York attorney noted for his defense of small investors against large corporations, died of cancer Nov. 20 in his home in Manhattan.

He began his career as a defender of small investors shortly after the stock market crash in 1929. In his first major case, he forced officers of the National City Bank to return $1.8 million in misused assets to small stockholders. For the next four decades Mr. Pomerantz successfully sued hundreds of officers of the nation's largest banks, Wall Street brokers, mutual funds, industrial companies and accounting firms.

"I love the buck," he was once quoted. "I'm out to make it. But with the money I've made I haven't forgotten that it's a hard cruel world and when it's a question of the rich against the poor, I'm for the poor."

He graduated cum laude from Brooklyn Law School in 1924 and founded the firm of Pomerantz Levy Haudek & Block in 1940. He also served as deputy chief counsel at the Nuremberg War Tribunals, and on the Advisory Committee on Rules of Practice and Procedure of the U.S. Supreme Court.

Survivors include his wife and two children.

Kumara P.S. Menon, 84, a retired career diplomat who had served as an ambassador to both China and the Soviet Union, died Nov. 21 at his home in Ottapalam, southern India, after a heart attack.

He was British Indian government representative to China from 1943 to 1947, and India's ambassador to the Soviet Union from 1953 to 1960.

Mr. Menon was president of the Indo-Soviet Cultural Society after his retirement from diplomacy and also chairman of the Indian Institute of Russian Studies. He attended Oxford University.
