Harry Grant Olds was born in Sandusky, a quiet town in Ohio, in 1868. He learned how to make tintypes at Willard A. Bishop’s photography studio, and opened his own studio when he was in his 20s. The economy was precarious and a recession made it worse, so Olds decided to head south. In 1899, on a steamer called Buffon, he traveled to Buenos Aires, taking 176 photographs along the way. Once there, Olds did photo portraits and commercial work. He also documented his new home. Until his death, in 1943, Olds tirelessly photographed the towns, cities, and people of Argentina and Chile, focusing especially on the working class and the way they lived in the first half of the 20th century. —Elena Clavarino
