David Policansky, born in Cape Town, South Africa, came to the United States for his higher education. He received a bachelor's degree in biology from Stanford University and master's and PhD degrees in biology from the University of Oregon. He has published more than 35 scientific papers. He also worked at the National Academy of Sciences in Washington, DC, where he contributed to about 60 published reports. He and his wife have long loved New Mexico, where they now live for half of the year, attracted by its spectacular landscapes and diverse and fascinating history and cultures. David began photographing New Mexico's historic adobe, stone, and brick churches in 2005 and has continued to do so, with increasing urgency as it becomes clearer that these churches do not last forever. This interest in New Mexico's churches led to his previous books, Historic Catholic Churches Along the Rio Grande in New Mexico and Historic Catholic Churches of Central and Southern New Mexico. He says that he is not a historian or a regular church-goer, but photographing New Mexico churches has deepened his appreciation of New Mexico's marvelous cultural and natural landscapes, including the fact that the descendants of these New Spanish/Mexican colonists have been here as long and are just as American as the descendants of the Mayflower pilgrims. He adds that when you consider the even longer history here of the Native Americans, you can begin to understand the complexity and profundity of the factors that have led to the presence of these beautiful buildings all over New Mexico.
