Isaac Parrish, Biographical Memoir, of John C. Otto… (1845)
“ Otto was its simplicity and truthfulness. A more conscientious man is perhaps rarely met with; as has been well remarked of him by one who knew him intimately, "his zealous love of truth made him scrupulously accurate in ascertaining and defining its exact limits, having a natural and excessive shrinking from anything that was false, which rendered candor and probity his distinguishing characteristics." ”
