Biography
Born in Iași, Romania, Yankwich received an LL.B. from Willamette University College of Law in 1909. He was in private practice in Modesto, California from 1909 to 1916, and in Los Angeles, California from 1916 to 1927, interrupted by service as a Sergeant in the United States Army during World War I, in 1918. He received a J.D. from Loyola Law School in Los Angeles in 1926. He was a judge on the Superior Court of Los Angeles County from 1927 to 1935.

On August 21, 1935, Yankwich was nominated by President Franklin D. Roosevelt to a new seat on the United States District Court for the Southern District of California created by 49 Stat. 508. He was confirmed by the United States Senate on August 23, 1935, and received his commission on August 24, 1935. He served as chief judge from 1951 to 1959, assuming senior status on April 28, 1964. On September 18, 1966, the districts of California were reorganized, and Yankwich was reassigned by operation of law to the United States District Court for the Central District of California. He continued serving in senior status on that court until his death, in 1975.

Important cases
Yankwich tried Cain v. Universal Pictures (1942), a case in which the writer James M. Cain sued Universal Pictures, the scriptwriter and the director for copyright infringement in connection with the film When Tomorrow Comes. Cain claimed a scene in his book where two protagonists take refuge from a storm in a church had been copied in a scene depicting the same situation in the movie. Yankwich ruled that there was no resemblance between the scenes in the book and the film other than incidental scènes à faire, or natural similarities due to the situation, establishing an important legal precedent.
