[1] His older brother, H. M. Eicher, was an assistant district attorney during the administration of President Grover Cleveland.

In 1932, Eicher was elected as a Democrat to the United States House of Representatives from Iowa's 1st congressional district.

[4] As his final congressional term ended, Roosevelt appointed Eicher to the United States Securities and Exchange Commission.

[2] New Dealers inside the Roosevelt Administration supported Eicher's wish to be chosen to fill one of two new seats on the United States Court of Appeals for the Eighth Circuit, but Iowa Senator Guy M. Gillette, who resented Eicher and Roosevelt for their unsuccessful efforts to purge him from Congress in 1938,[6] stood in the way.

[10] At the time of his death, Eicher had presided for over seven months at the trial of 30 suspected Axis conspirators and sympathizers.

[11] After the war ended, the government chose not to prosecute again, and Judge Bolitha James Laws dismissed the charges against the defendants.
