<p>Library of Congress description: "Editorial staff of the <a href="https://en.wikipedia.org/wiki/New_York_Tribune" class="extiw" title="en:New York Tribune">New York Tribune</a>. Seated, left to right: George M. Snow, financial editor; <a href="//commons.wikimedia.org/wiki/Bayard_Taylor" class="mw-redirect" title="Bayard Taylor">Bayard Taylor</a>; <a href="//commons.wikimedia.org/wiki/Horace_Greeley" class="mw-redirect" title="Horace Greeley">Horace Greeley</a>; <a href="//commons.wikimedia.org/wiki/Category:George_Ripley" title="Category:George Ripley">George Ripley</a>, literary editor; Standing, left to right: <a href="https://en.wikipedia.org/wiki/William_Henry_Fry" class="extiw" title="en:William Henry Fry">William Henry Fry</a>, music editor; <a href="//commons.wikimedia.org/wiki/Category:Charles_Anderson_Dana" title="Category:Charles Anderson Dana">Charles A. Dana</a>; <a href="https://en.wikipedia.org/wiki/Henry_Jarvis_Raymond" class="extiw" title="en:Henry Jarvis Raymond">Henry J. Raymond</a>.  Identified and dated by comparison with known likenesses: Greeley in Holden's dollar magazine, 1849; Dana in Scribner's magazine, 1895, p. 442; Raymond in Frank Leslie's illustrated newspaper, Aug. 23, 1856, p.176. The identification of Snow is based on his inclusion in Brady's list of those in this picture and his apparent age. The identifications of Ripley and Fry are based on their inclusion in Brady's list and resemblance to identified portraits of them as much older men.

Harold Francis Pfister, <i>Facing the light : historic American portrait daguerreotypes</i> (Smithsonian Institution Press, 1978), page 323, identifies the men as "[Horace Greeley] with six journalists of the Tribune staff, including: Bayard Taylor (seated, second from left), George Ripley (seated, right), William Henry Fry (standing, right), and Charles A. Dana (standing, center)."
