An obituary about Paul Landon Banfield in Wednesday's editions of The Washington Post failed to state that the family suggests that experssions of sympathy be in the form of contributions to the Paul L. Banfield Scholarship Fund at the Landon School, 6101 Wilson Lane, Bethesda, Md. 20014.

Paul Landon Banfield, 77, founder of the Landon School for Boys and its headmaster for 41 years, died yesterday at Sibley Memorial Hospital. He had suffered from a lung ailment.

Mr. Banfield, an athele and scholar, graduated from St. John's College in Annapolis in 1923, and completed graduate work at George Washington and Harvard Universities. Unable to continue onto medical school because of finances, he decided to devote himself to teaching.

He tutored English students for Madeira Wing, founder of the Madeira School in suburban Virginia and she encouraged him to start his own school.

In 1929, Mr. Banfield borrowed $2,000 and founded the Landon School for Boys on Massachusetts Avenue NW, begining with 23 boys. At the end of the first month he had dismissed six of them for failing to meet the standards he set in a regiment that included reading, writing, arithmetic, integrity, courage, sacrifice and self-discipline.

In 1934, he moved the school to Bethesda to achieve a country day school atmosphere. The school has grown to a present enrollment of 570.

Mr. Banfield served on the Board of Economic Warfare in 1942, and in the Army Air Corps for the next two years, rising to the rank of major.

He was one of the founders of Suburban Hospital in Bethesda, was president of the board of governors of St, John's College and the board of trustees of Mount Vernon Colleges here.

After his retirement as headmaster of London School, he remained on its board of trustees, serving as president of the nonprofit Landon School Corporation.

Mr. Banfield was a member of the Chevy Chase Club, the Cosmos Club and the Georgetown Assembly.

He is survived by his wife, Mary Lee Banfield, of the home on the Landon campus in Bethesda.
