Newton I. Steers Jr., 76, a Montgomery County Republican and political activist who had served six years in the Maryland Senate and one term in the U.S. House of Representatives, died of cancer yesterday at his home in Bethesda.

Mr. Steers was a primary player on the state and regional political stage from the early 1960s into the 1980s.

He was Maryland's insurance commissioner for three years before his 1970 election to the state Senate.

He served there until 1976, when he was elected to Congress. He was defeated in a bid for reelection in 1978 and then lost again in a 1980 bid to reclaim his seat.

In 1982, he was the Republican nominee for lieutenant governor of Maryland, but he lost in the general election.

An investor with a law degree who made a fortune in mutual funds during the 1950s, Mr. Steers had a reputation as a hard-working and independent-minded politician with a prickly unpredictability. He was known as a gadfly and a needler with a quick and nimble wit and a sharp and sometimes sarcastic tongue.

Ideologically, he was a Republican liberal who during his one term in the House of Representatives compiled the highest liberal voting record of any House Republican, according to a study by Americans for Democratic Action.

In his personal demeanor, he was charming, engaging and articulate, whether shaking hands on the campaign hustings or socializing at the Chevy Chase or Metropolitan clubs. In Annapolis, he was said to have appeared on occasion in the lounge of the Maryland Senate, tennis racket in hand, looking for a match.

Mr. Steers was born in Glen Ridge, N.J. He graduated from Yale University. He worked for Du Pont Co. subsidiaries in New Jersey and Delaware before World War II. During the war, he served in the Army Air Forces, which sent him to the Massachusetts Institute of Technology to study meteorology. Later he served in England, France, Belgium and Germany.

After the war, he graduated from Yale Law School. He was assistant works manager of the General Aniline & Film Corp. in Binghamton, N.Y., before moving to Washington in 1951 to work for the Atomic Energy Commission.

Two years later, Mr. Steers and a group of friends formed the Atomic Development Mutual Fund, which was to specialize in "securities of companies participating in activities resulting from the natural sciences."

The fund was an immediate success, and Mr. Steers traveled the world visiting investors and brokerage firms to promote investment in atomic energy. By the time the fund was 19 months old, it had 30,000 shareholders and $44 million in investments.

In 1965, Mr. Steers, by then worth more than $2 million, sold his interest in the fund for $300,000.

In 1957, he married Nina Auchincloss Gore, the half-sister of writer Gore Vidal and stepsister of Jacqueline Kennedy Onassis. Mrs. Kennedy was matron of honor at the wedding and then-Sen. John F. Kennedy (D-Mass.) was one of the groomsmen.

In the early 1960s, Mr. Steers became active in the legislative reapportionment movement in Montgomery County. In 1962, he ran for Maryland's at-large seat in Congress. He lost to Democrat Carlton R. Sickles. In 1964, he became Maryland's Republican state chairman. He held that post for two years.

In 1966, Mr. Steers lost a race for Congress, but the next year he was named insurance commissioner by then-Gov. Spiro T. Agnew.

In that job, Mr. Steers said, "My philosophy was, I turned down every rate increase I could legally . . . All in all, on the job, I got a great deal of publicity, and I enjoyed it."

In 1970, Mr. Steers served briefly as assistant secretary of the newly created State Department of Licensing and Regulation before his election to the Maryland Senate.

His first marriage ended in divorce in 1974.

Survivors include his wife, Inge Gabriele Wirsich Irwin Steers, whom he married in 1978, of Bethesda; three sons from his first marriage, Newton Ivan Steers III and Hugh Auchincloss Steers, both of New York, and Burr Gore Steers of Hollywood; and a stepson, Kristof Andreas Irwin of College Park.

From 1930 to 1948, she was a social worker with the D.C. Department of Public Welfare. She was a medical social worker at Garfield Hospital from 1948 to 1955, and from 1955 to 1966 she worked for the D.C. Department of Public Health as a social worker operating mainly out of D.C. General Hospital.
