"Daniel Senise at work throwing a switch at an Indiana Harbor Belt Line railroad yard."
The Library of Congress archive uses the spelling "Senise," but it is Sinise. Sinise was the grandfather of actor Gary Sinise. You won't get that from the national archive or Shorpy, but you can trust me on this one.
Delano shot a series of Sinise family photos, including this image of Gary's father, Robert Sinise.
