The Arion Trio
These three young ladies organized as a chamber music group while attending
Oakland Technical High School in 1918. They first appeared on radio over
Oakland's KLX in 1924, and they soon became a program staple on that station.
Their popularity led them across the Bay to NBC's KGO (1924-1925), and they were
heard six days a week on the Pacific Coast networks during the 1930s.
trio originally consisted of violinist Josephine Holub, pianist Joyce Barthelson
and cellist Margaret Avery. According to the Encyclopedia of American Radio,
1920-1960, Auro Craverot replaced Margaret Avery (at right in the above

later years, Barthelson became an acclaimed composer and arranger.
Avery, whose married name was Margaret Avery Rowell (1900-1995), later
served on the faculties of the University of California, Stanford
University, Mills College and San Francisco State University.
In the early 1950s, she helped found the California Cello Club, the
first organization of its kind in the nation. Her "whole body" technique
for playing the cello, known widely as the Rowell Method, has been used
to teach several generations of students around the world. She was also
an avid wilderness hiker and nature enthusiast; her son,
(1940-2002), was a legendary wilderness photographer and adventurer
whose works were often featured in National Geographic.
On the occasion of her eightieth birthday, a concert featuring eighty
cellists was performed in Mrs. Rowell's honor at the San Francisco
Conservatory of Music, where she taught for fourteen years. She retired
from the Conservatory with an honorary doctorate. In the photo, at
