During his 45-year career at the Star, beginning in 1911, HCH, as he was known, rose from cub reporter to managing editor and after the death of owner/editor Joseph E. Atkinson in 1948, he served for nearly nine years as president of the company.

At the top of its front page, it ran five photos of the Bremen, its crew and local people who greeted the plane when it first landed, trumpeting its achievement under a heading that read: "Most remarkable news-picture scoop in newspaper history.
