Seebohm became president of the chamber of commerce at Braunschweig and was a member of the Landtag state assembly of Lower Saxony from 1946 until 1951.

From 1946 until 1948 he held the office of Minister for Reconstruction, Labour and Health in Hinrich Wilhelm Kopf's Lower Saxon state government.
