[1] Born in Biloxi, Mississippi, Thomas was the third of eight children of Croatian immigrants who came to America in 1903.

He worked as a minor sports coach and physical education instructor while in college.

[4] Thomas entered politics and was successful in his first run for office in 1940, resoundingly defeating Charles M. Smith to become the State Assemblyman for the 68th District representing San Pedro.

Ultimately, he served in the Assembly for 19 consecutive terms, until his first defeat in a re-election bid by Republican candidate Gerald N. Felando in 1978.

[6] Originally slated to be called the "San Pedro-Terminal Island Bridge" when construction began in 1960, in 1961 the California Legislature passed Concurrent Resolution 131 naming the suspension bridge planned between San Pedro and Terminal Island for Thomas in honor of his foresight and untiring work that culminated in its construction.
