"Helen Hay was a highly skilled arts-and-crafts practitioner whose designs played an important role in creating The Evergreen: A Northern Seasonal (1895-96/7) and realizing its socio-political mission of revitalizing Edinburgh Old Town specifically, and Scottish culture more broadly, through the renewal of Celtic ornament and its applications (See General Introduction to The Evergreen). Despite her significant artistic contributions to the architecture of The Evergreen’s printed page and Edinburgh’s built environment, however, Helen Hay remains a largely unknown Scottish designer." - Biography by Kooistra on the Yellow 90s website.

"George Willard Bonte, illustrator, designer, author, who was art director of the old New York Herald from 1906 to 1920, died yesterday afternoon at his home, 310 West Ninety-ninth Street, after an illness of several weeks. He would have been 73 years old on May 16. Born in Cincinnati, Mr. Bonte was educated at the Cincinnati School of Technology, Cincinnati Art School, and the Art Students League in this city. In 1894 he joined the staff of The Cincinnati Tribune. Two years later he came to New York and went to work on Outing Magazine. In 1900 he began his long association with The Herald. He was vice president and a director of the James Gordon Bennett Memorial Fund for New York Journalists. After leaving The Herald Mr. Bonte was art manager for the publicity and advertising departments of the Selznick Pictures Corporation, 1920-23, and art manager for Warner Brothers Motion Pictures, 1923-31. In recent years Mr. Bonte had been engaged principally in the preparation of brochures and articles for advertising agencies, publicity groups and magazines. The work usually involved historical or other form of research, and the planning of illustrations, in addition to the writing. The most important product of this last period was Mr. Bonte's book, published in 1936, “America Marches Past. A pictorial review of America through the ages." It contained the results of much delving into old tomes, searching of yellowed newspapers, looking for the "vital historical pictures hidden away on the dusty shelves of American libraries and museums." Beginning with Agassiz's claim that North America was the "first born among the continents" he carried the story to the political conventions of the summer of 1936. In January, 1933, it was revealed that the self-effacing West Side resident who enlisted the sympathy of Mayor John P. O'Brien in behalf of the twenty men living in their own shanty colony along the Hudson River north of Ninety-sixth Street, was Mr. Bonte. He and a group of his friends had been helping the men maintain their independent mode of living since the previous August. During the first World War Mr. Bonte was chairman of the board of representatives of the News Photographic Agencies handling official photographs. He leaves a widow, who was Marie Louise Quarles at their marriage in 1902." - Obituary from the New York Times
