In The World Encyclopedia of Cartoons, Volume 2 (1983) Maurice Horn profiled Albert Carmichael. Like the other profiles in the book, the sources of information were not mentioned. Using Ancestry.com and Google, I found sources that support some of the details in the profile, and I have found information regarding Carmichael's wife and son. What follows are excerpts from Horn's profile of Carmichael. My comments appear parenthetically.
CARMICHAEL, ALBERT PETER (1890-1917) American cartoonist born in Albany, New York, on December 13, 1890. Albert P. Carmichael started his cartooning career with the New York World when he was not yet 17. Among his co-workers on the World art staff were Gus Mager, Jack Callahan and George McManus, whose style Carmichael greatly admired and endeavored to emulate.
(Carmichael's full name is correct. The Washington Post reported, on October 26, 1974, the death of his wife. "Myra C. Carmichael, the widow of Albert Peter Carmichael, a cartoonist for the old New York World, died Thursday night at Sands Point Nursing Home at Sands Point, N.Y. She was 84." The month and year of Carmichael's birth is confirmed by the 1900 U.S. Federal Census. He, his mother and brother lived with his maternal grandmother in Malta, New York. In the 1910 census, Carmichael's birthplace was recorded as "Albany, N.Y." He, his mother and grandmother lived in the Bronx, New York City at 1000 Simpson Street. His occupation was artist at the World.)
Carmichael contributed cartoons and spot illustrations to the columns of the World, as well as a number of panels and comic strips, including Jay Jones and His Camera (1908) and Why Be Discontented (1907), The Ambitions of Sonny and Sue (1908), Our Funny Language, Dr. Spook's Explorations (1909), Rosie, the Joy of New York Life (1911) and…Everybody's Doing It! (1912). Carmichael is best noted for his continuation of McManus's The Newlyweds and Spareribs and Gravy which he took over in 1912. Carmichael died on February 3, 1917, from complications of an appendicitis operation, at the age of 26.
(At Ancestry.com there is a family tree for Carmichael; the tree has the same death date, plus the location as Los Angeles, California. He married Myra Cordes around 1916; the Washington Post said, "Mrs. Carmichael was an artist for the World, an actress in silent films and an active suffragette in the days before World War I." In the book Silent Film Necrology (2001), her entry is, "Carmichael, Myra [actress] (b. 22 Jan 1890-22 Oct 1974 , Port Washington NY). AS, p. 205 (d. 25 Oct, LA CA). BHD1, p. 605."
