## History
### Union Bank

In 1914, Kaspare Cohn founded Kaspare Cohn Commercial & Savings Bank in Los Angeles. It was renamed Union Bank & Trust Company of Los Angeles in 1918. Harry Volk was recruited from Prudential Insurance Company as the bank's new CEO in 1957 and pioneered the use of the one-bank holding company, among other banking innovations. Volk retired in 1980 after the purchase of the bank by London-based Standard Chartered Bank in 1979.

### MUFG Bank, Ltd.

The Bank of Tokyo established the Bank of Tokyo California in 1953 in San Francisco.
