A landmark sale features rare examples of works by 19th and 20th-century American masters of the medium, including Alfred Stieglitz, Edward Steichen, Dorothea Lange, Edward Weston, Paul Strand and many more

The first few decades of the 20th century were a fruitful period of artistic production for the still-fledgling art of photography. In New York City, just after the turn of the century, a small circle of photographic visionaries revolved around the magnetic figure of Alfred Stieglitz, whose influence as artist, patron and gallerist galvanised the tight-knit community. Stieglitz was absolutely central to both the Photo-Secession, an early-1900s movement that was known for works in the style of Pictorialism, as well as the development of photographic art along modernist lines.

Stieglitz was immensely influential in establishing and tirelessly promoting photography as an art form in the United States. He edited and published magazines, promoted photographers through exhibitions at his galleries, and produced his own rich body of creative photographic work. The photogravure printing process was his well-known favoured method, and he promoted the technique as an original means of photographic printmaking.

Included in the sale are prints of The Terminal (1892), The Hand of Man (1902), and the artists’ own print of The Steerage (1907).

These key prints come to auction alongside rare examples of works by Steiglitz’s counterparts in the Photo-Secession, including Edward Steichen, Gertrude Käsebier and Clarence White, and Modernist masterworks by Edward Weston, Paul Strand and Charles Sheeler.

The collection of Diann and Thomas Mann is one of the most significant collections of masterworks of American photography in private hands. With an emphasis on Pictorialism, the birth and explosive growth of Modernism and the critical transition between the two, the collection is a study of the depth and breadth of the artistic vision of many of the most significant photographers of the 20th century. All told, it forms a comprehensive visual record of a rich period of production before the First World War, through the explosive and radical period between the two great wars, and into the heady post-war period.

The earliest acquisitions in the Mann collection are from the 1970s, a time when no more than a handful of photography dealers existed and photography itself was not seen as a valuable investment. Enthralled with the camera from an early age, Thomas Mann educated himself in the history of the medium. 

He moved quickly from collecting monographs on his favourite photographers to the realisation that early prints of historical works were not only readily available, but relatively inexpensive. In many cases, the Manns gravitated to prints that stand out not just for their iconic imagery, but also for their signatures, annotations, pristine condition and distinguished provenance.

The curiosity of Thomas and Diann Mann, coupled with their willingness to acquire, was prescient — especially as the availability of superb early examples became increasingly rare. Indeed, so rare are the masterworks in this collection that it would be nearly impossible to recreate it today. The sale of the Mann Collection is a landmark event, offering new and veteran collectors alike the opportunity to acquire some of the most important images in the history of the medium.
