CARLTON DUNFIELD DETHLEFSEN
Carlton Dunfield Dethlefsen, whose offices are situated at 881 Mills building in San Francisco, has acquired a
most substantial success in the practice of law in this city within the comparatively short period of nine years.
He is a native of this city, his birth having occurred June 7, 1891, and he is a son of Nicholai Frederick and
Emma Elizabeth (Dunfield) Dethlefsen.
Nicholai F. Dethlefsen came to California in the year 1885, and here he married Emma Elizabeth Dunfield, who was
born in Seattle, Washington, of pioneer stock. For a number of years, they conducted a hotel "south of Market
Street." Both of the parents are yet living, the father having attained the age of seventy seven and the mother
sixty five. Carlton D. Dethlefsen's maternal great grandfather, Samuel Dunfield, was one of the prominent pioneers
of the northwest, and his grandmother was the first white woman to be carried by natives across the Isthmus of
Panama, en route to California.
Canton D. Dethlefsen, who was the only child born to his parents, attended the old Lincoln school of San Francisco,
his class having been one of the last to graduate from this institution so fondly remembered by San Francisco citizens.
He also attended the Edison public school, and in 1906 graduated from the Horace Mann high school. From September,
1911, until September, 1913, he studied at the University of California, and then entered Washington and Lee University
in Lexington, Virginia, for a year's course. Having decided to make the practice of law his life's work, Mr. Dethlefsen
took up the study of law in the office of John F. Peck and William Bunker in Oakland, California, and in 1915 passed
the state bar examination and was duly admitted to practice.
After the United States declared war against Germany in 1917, Mr. Dethlefsen enlisted in the United States Navy
as a second class seaman. He served for a period of two years and three months, at the end of which time he was
honorably discharged with the rank of ensign. He then returned to the office in Oakland which he had left, that
of Peck, Bunker & Cole, and remained from 1919 until 1922. In the latter year, he opened his office in San
Francisco, and here he has met with constantly increasing success, and has conducted litigation for a very large
clientele. He is a member of the American, the California State, and the San Francisco Bar Associations. In business
affairs, he has taken an interested part in his capacity as an attorney, and is now a member of the advisory board
of the Broadway and Grand avenue branch of the Bank of America.
In San Diego, California, November 29, 1919, occurred the marriage of Mr. Dethlefsen and Miss Frances Adele Harmon
of Cincinnati, Ohio, the latter a daughter of Dr. Frank W. Harmon and a niece of the Hon. Judson Harmon, former
governor of Ohio, eminent judge, and attorney general of the United States under President Cleveland. Mr. and Mrs.
Dethlefsen are the parents of three children: Elizabeth Harmon, who is eleven years of age; Carlton D., Jr., a
lad of five years; and John Frederick, who is in his first year.
Mr. Dethlefsen is a thirty second degree member of the Masonic fraternity, and belongs to the Mystic Shrine, the
Masonic Club, the Order of Sciots, the American Legion, the South of Market Boys, the Commonwealth Club, the California
Golf Club, and the Phi Delta Theta and Gamma Eta Kappa fraternities. In the companionship of his family and in
the atmosphere of his own home, he has found his greatest relaxation and diversion from his arduous professional
duties, and he has also been a devotee of golf.
