Schumacher’s interest in the tumult of America in the 1960s was also evident in ''The Contest: The 1968 Election and the War for America's Soul'', forecasting the current era of media as entertainment over analysis, bipartisanship's unravelling, and public cynicism over electoral politics. His other biographies included
Francis Ford Coppola: A Filmmaker’s Life,
Will Eisner: A Dreamer’s Life in Comics,
Al Capp: A Life to the Contrary, and
Mr. Basketball: George Mikan, the Minneapolis Lakers, and the Birth of the NBA. Schumacher’s lifelong home near
Lake Michigan influenced his decision to write a series of
Great Lakes shipwreck histories, including one on the pop-song-famous Edmund Fitzgerald:
Mighty Fitz: The Sinking of the Edmund Fitzgerald. Others were: ''Too Much Sea for Their Decks: Shipwrecks of Minnesota's North Shore and Isle Royale
; Wreck of the Carl D.: A True Story of Loss, Survival, and Rescue at Sea
; November's Fury: The Deadly Great Lakes Hurricane of 1913
; Torn in Two: The Sinking of the Daniel J. Morrell and One Man's Survival on the Open Sea
; and Along Lake Michigan: Shipwreck Stories of Life and Loss
