John Vignoles, a direct descendant of the engineers who designed and built the Bahia and San Francisco Railway - and hired Mulock to photograph the works - joined forces with Sabrina Gledhill to co-author an essay on "Ben" for the Encyclopedia of Nineteenth-Century Photography (ed. John Hannavy), which will be published in August 2007. Sabrina also wrote an essay on the Swiss-born Brazilian photographer Guilherme (Wilhelm) Gaensly for the encyclopaedia. According to the publishers (Routledge):
The Encyclopedia of Nineteenth-Century Photography is the first comprehensive encyclopedia of world photography up to the beginning of the twentieth century. It sets out to be the standard, definitive reference work on the subject for years to come.
Its coverage is global – an important ‘first’ in that authorities from all over the world have contributed their expertise and scholarship towards making this a truly comprehensive publication. The Encyclopedia presents new and ground-breaking research alongside accounts of the major established figures in the nineteenth century arena.
Coverage includes all the key people, processes, equipment, movements, styles, debates and groupings which helped photography develop from being ‘a solution in search of a problem’ when first invented, to the essential communication tool, creative medium, and recorder of everyday life which it had become by the dawn of the twentieth century.
The sheer breadth of coverage in the 1200 essays makes the Encyclopedia of Nineteenth-Century Photography an essential reference source for academics, students, researchers and libraries worldwide.
