A Dire Threat, 1904, by A. Z. Baker, who has no link anywhere, at least not one I feel like finding, so let's look at his entry in the encyclopedia I took these cartoons from.
“
ALFRED ZANTZIGER BAKER (1870-1933) American cartoonist born in Baltimore, Maryland. “Baker-Baker” (as he became known from his monogrammed signature of two
Bs back to back) was co-educated in private schools and studied art at the Charcoal School in Baltimore the
Académie Julian and the
Ecole des Beaux-Arts in Paris.
“Baker pursued serious art and was exhibited at age 23 in the National Academy (later exhibitions were sponsored by the
Société des Artistes Français and the Salon des Artistes Humoristes), but he joined the staff of
Puck in 1898. As a cartoonist he did not confine his work to one outlet, and at the turn of the century he was appearing in
Puck, Judge, Life, Scribner's, Harper's, Century, and
St. Nicholas. His books include
The Moving Picture Book (1911),
(1912), and
The Torn Book (1913). His innovations—such as die-cutting and 3-D drawings with glasses—are surpassed in the children's book genre only by those of the imaginative
Peter Newell.
A.Z. Baker stated that he was influenced by French and Japanese cartoons (indeed, he often worked Japanese motifs into his drawings), but whatever the influences, it must be recorded that his work was among the freshest and cleverest of American cartooning at the turn of the century—and retains these characteristics even under modern scrutiny. He rejected the fine-line illustrator's then threating to stifle freedom of line and rendered his cartoons—which were almost exclusively animal gags—with a lush brush line, shaded with crayon on a coarse board. He had a delightful and visually agreeable sense of design and anatomy; his funny animals romped with animation among the solid society of drawings in the magazines. In this sense he helped forge a new spirit of amiable looseness in American magazine cartooning and was soon in the company of such men as
Art Young, Leighton Budd, and
Hy Mayer.”

Perry Barlow for
The New Yorker, who also doesn't merit a link.
“
PERRY BARLOW (1892-1977). American cartoonist born in McKinney, Texas, near Dallas. Perry Barlow, who was famous for his many
New Yorker cartoons and covers, was raised on his family's farm and spent his boyhood in Texas. He traveled to Illinois to attend the
Art Institute of Chicago and there was part of a remarkable class that included
Helen Hokinson and
Garrett Price, also destined to be
New Yorker greats. He met his wife,
Dorothy Hope Smith, at the art school; she later became a famous portraitist of children best known for her drawing of the baby on the Gerber Trademark.
“Around 1920 the Barlows moved to New York, and he began a career of freelance cartooning and illustrating. At the Art Institute of Chicago he discovered that he was color blind, so his color work, featuring soft muted pastels, was done by his wife (and after her death by the watercolorist Catherine Barr). As success came the family joined the growing artists' community of Westport, Connecticut.
“James Geraghty, art editor of
The New Yorker from 1939 to 1973, Has commented that Perry Barlow was “a shy, aloof man” but still a great artist with children.”
The New Yorker's [then current] editor,
William Shawn, regarded Perry Barlow as 'one of our three or four most prolific people.' Ironically, although he had an opportunity to publish an anthology of his cartoons, Barlow was always lukewarm on the project, and no anthology exists. From the 1920s until the early 1970s, however, his cartoons appeared in a variety of magazines, including
Saturday Evening Post and
Collier's. Fortunately the general anthologies of such magazines contain generous samplings of his works.
“Barlow's cartoons have a loose, sketchy style and soft, understated wash. Children were a favorite theme in his cartoons, which were usually geared more for a chuckle than a belly laugh and always displayed a refined, sophisticated sense of humor. His accomplishments as a
New Yorker cover artist helped set the style for the magazine, along with covers by Peter Arno, Helen Hokinson and others. A Barlow cartoon was a humorous cartoon that needed no caption and captured some of the joy of living that appears to a cartoonist with an eye for it. Today, when the
New Yorker's covers are often devoted to design sans humor, one can appreciate Perry Barlow's gentle cartoon covers all the more.”

Before
Stan and Jan Berenstain did children's books, they did lots of gag cartoons for magazines like
McCall's.

Roland Berthiaume, for
La PatrieAgain, no information about him online, so...
“
ROLAND BERTHIAUME (1927-?) French-Canadian cartoonist born in Montreal, Quebec. Better known as “Berthio”, Roland Berthiaum attended Ste. Marie College (now known as the
University of Quebec) in Montreal before embarking on a commercial art career. After attending night classes at Montreal School of Arts, Berthiaume spent a year in Paris (1951-52).
“In 1953 Berthiaume started his career with editorial cartoons in the weekly
L'Autorité du Peuple, also contributing occasionally to such publications as
La Semaine à Radio-Canada and
Le Travail. He finally found his métier with the political cartoons he published in the political weekly
Vrai. There Berthiaume was responsible for two pages of cartoons, usually four in number, dealing mainly with city problems. Berthiaume collaborated on
Vrai from its inception in October 1954 to its demise in May 1959. He then went to the Montreal daily
La Presse, where until 1967 he contributed
Drôle de Journée(“Some Funny Day”), a column in the form of caricatural drawings and cartoons commenting on daily happenings.
“In 1967 Berthiaume returned to editorial cartooning, first for the daily
Le Devoir, then for the pro-independence daily
Le Jour (1974-76) and finally for
Montréal-Matin. He has also worked for several magazines (
Time,MacLean's). Two collections of his caricatures have been published:
Un Monde Fou (“A Mad World”, 1961) and
Les Cent Dessins du Centenaire (“The One Hundred Drawings of the Centennial”, 1967.
“Like
Robert LaPalme, Berthiaume has always been concerned with form as well as with content. He was the first Canadian cartoonist to engage in character with a social thrust. Twice a winner at the International Salon of Caricature in Montreal (1964 and 1966), Berthiaume was the recipient of the
Oliver Asselin Journalism Award in 1973.”
