The Straus National Bank and Trust Company was a financial institution based in Chicago, Illinois.

[2] In 1973, the Walter E. Heller International Corporation acquired the American National Bank and Trust Company of Chicago.

[1][6] At the close of business on November 21, 1929, the Straus National Bank and Trust Company had reported deposits of $17,952,297, and undivided profits of $573,778.

[11] In a 4 to 2 split decision, on May 11, 1973, the Federal Reserve Board approved the Walter E. Heller International Corporation's acquisition of the American National Bank and Trust Company of Chicago.

Under decision, Heller International became a bank holding company, with orders to divest itself of its manufacturing subsidiaries within two years.

[3] Two days after the Walter E. Heller International Corporation purchased of Chicago's American National Bank, on August 3, 1973 it was reported that Heller was undergoing management changes, with some officers in American National also taking positions in the holding company, "including Allen P. Stults, 60, who was named president, and William G. Ericsson, 46, executive vice president."

[13] In 1981, the New York Times reported that "restrictive legislation governing interstate and intrastate branch banking has forestalled Heller's efforts to make its ownership of the American National Bank and Trust Company in Chicago a truly integrated part of its organization.

[4][5][14][15] The bank had a successful year in 1984, serving "middle market" companies that were small and medium in size.
