In memory of
Berthelsdorf, Siegfried 99 06/16/1911 01/31/2011 Dr. Siegfried Berthelsdorf died peacefully at his Portland home. He was 99. Siegfried was born in Shannon County, Mo., to Richard and Amalia Berthelsdorf, German immigrants who homesteaded in Klamath Falls, where he grew up. Playing trombone in a dance band to support himself, he graduated from the University of Oregon (Bachelor of Arts with Phi Beta Kappa 1934, Master of Arts and Doctor of Medicine 1939) and continued studies in psychiatry in New York City, graduating from the New York Psychoanalytic Institute in 1952. He was a former U.S. Army Air Corps major, having served as neuropsychiatrist and flight surgeon from 1943 to 1946. While stationed in Tampa, Fla., he met and married Mildred Friederich. After several years in New York City, the couple and their three children moved to Portland in 1953, where Siegfried began private practice as the first psychoanalyst in Oregon. He was a founding member of the Oregon Psychoanalytic Foundation and a training and supervising analyst with the Seattle Psychoanalytic Institute. Active throughout his life as a psychotherapist, consultant, teacher and mentor with numerous organizations in the field of mental health in Portland, he, along with Mildred, was also a contributor to the development of Portland's cultural growth, serving on the boards of the Portland Opera Association, Portland Chamber Orchestra and American Rhododendron Society (Portland chapter). As both volunteer and professional, he received many awards and citations for his valuable work. Some of his happiest times were spent working his farm near McMinnville, which he purchased in 1962, fulfilling a lifelong dream. Predeceased in 2005 by Mildred, his wife of 60 years; and his sister, Gretchen, he leaves his children, Richard, Victor and Dianne; five grandchildren; sister, Lydia; three nephews and a niece; and his dear friend, companion and caretaker, Felicia Wirtz. We are left with a multitude of loving memories and a sense of great loss. The family thanks Dr. Steven Freer for his kindness, respect and compassion for Siegfried, and we particularly thank the faithful friends who visited him over his last five years. Our gratitude to Felicia is boundless. A private memorial is planned. In lieu of flowers, please consider a donation in Siegfried's memory to the Boverman Endowment Fund at the Oregon Psychoanalytic Center, 503-229-0175, or the Berthelsdorf Memorial Trophy fund at the Portland chapter of the American Rhododendron Society, in care of Ann Clack, 503-656-3891.
