Painter, illustrator, and printmaker Bertha Lum is recognized for her color woodblock prints utilizing Chinese and Japanese techniques. Much of her artwork reflects the style of classic Japanese ukiyo-e prints, depicting landscapes, women, kabuki actors, sumo wrestlers, and more.

Bertha Lum (1869-1954), “Three Wise Men,” color woodblock print on paper. Sold for $1,200 in A Collection of Fine Art & Jewelry, July 28, 2021.


Bertha Boynton Bull was born in 1869 in Tipton, Iowa. Both of her parents were non-professional artists. She worked as an artist from 1890 to 1895 in Duluth.

In 1895, she registered in the department of design of the Art Institute of Chicago, studying with Anne Weston and Frank Holme. Bertha Bull married Burt Lum in 1903; the newlyweds went to Japan for their seven-week long honeymoon, where she wanted to learn the classic ukiyo-e method from a printmaker.

Lum’s early prints were simplified improvisations on ukiyo-e classics, but the results were highly effective and poetic. On a return to Japan 1907, a professor from the Imperial Art School in Tokyo introduced Lum to Igami Bonkutsu, a block cutter in Yokohama. Lum worked with Igami for two months, and followed this apprenticeship with one with Nishimura Kamakichi. Lum’s images from this period are focused on soft variations of tone and color, eschewing the black outline block of traditional ukiyo-e. 

Lum’s woodcuts were the only foreign items in the Tokyo Tenth Annual Art Exhibition in 1912; she was also the only female artist to participate. Later in the same year, her work was shown in a solo exhibition in Chicago and New York City at the Albert Roullier Art Gallery and the Katz Gallery. In 1915, Lum’s prints were shown in Panama-Pacific International Exposition San Francisco, for which she was awarded a silver medal. Her work was also included at the Art Institute of Chicago’s Exhibition of Etchings and Block Prints in 1919.

The Lum family moved to San Francisco in 1917; in 1920, she made one of her popular prints there, “Point Lobos.” With her daughter, Bertha Lum went to China in 1922. She developed a technique there for “raised-line” prints, which feature block outlines hand-colored using watercolor. In 1922, her first illustrated book, Gods, Goblins, and Ghosts, was published, based on her travels in Japan.

In 1936, Lum’s second book, Gangplanks to the East, was published, a collection of travel stories and Asian folklore tales. Her eyesight began to deteriorate after 1937, ending her ability to create prints. Bertha Lum died in Genoa, Italy, in 1954 at the home of her older daughter.

Lum’s works are present at the Smithsonian Museum of American Art, the Fine Arts Museums of San Francisco, the Library of Congress, and private collectors. She was a member of the Print Makers Society of California, the California Society of Printmakers (then known as the California Society of Etchers), and the Asiatic Society of Japan.

Her images are detailed with rich and vibrant color with impeccable precision and techniques of Japanese woodcut techniques.
