Born in Beverly, MA. Perez Batchelder, Freeman's older brother entered Daguerreian trade in Boston around 1844 with his brother Benjamin. Both brothers were in California by 1851. By 1852, the firm of P.M. and B.P. Batchelder was operating in a daugerreian car near the Stockton House in Stockton, California. Later, after 1853, P.M. Batchelder and Company continued business in the Stockton downtown. In the early 1850s, news of gold discoveries in Australia enticed many Californians to try their luck on that distant continent, including Perez Batchelder, who sailed from San Francisco on the "Rover's Bride" and landed in Sydney in 1854. In Melbourne, Batchelder established a daguerreian gallery and he soon became the premier gallery in the city. Business was apparently thriving enough in 1865 to entice his brothers Benjamin, Nathaniel, and Freeman Batchelder to come to Melbourne to assist Perez. Perez and Freeman were the name partners in the gallery in 1857, but by year's end, photographer Daniel O'Neill had become a partner in the firm and Perez had left Melbourne for America. Freeman Batchelder continued as a partner in the Batchelder and O'Neill gallery until his untimely death at sea in 1862. Batchelder and O'Neill continued under O'Neill's supervision until around 1866, when Charles E. Johnson purchased the business.
