Julia Jacobs Harpster went to India as a Lutheran missionary with her husband in 1893, based at
Rajahmundry. She was superintendent of the Industrial School for Mohammedan Women, which taught gold and silver embroidery and other handwork skills to Muslim widows and other women in need of paid employment; she also supervised a bookstore in Rajahmundry and raised funds for the mission's work there with the sale of
postcards depicting Indian scenes. "The silent influence of her winsome Christian spirit is a potent factor among her heathen pupils," a denominational publication wrote of Julia Harpster. In 1902, she published a book of photographs,
Among the Telugoos: Illustrating Mission Work in India. She and her husband were credited with founding "India Lace Day", an annual observance in American Lutheran churches where funds were raised for women lacemakers in India, and shipments of supplies were sent for their use. The Harpsters retired from their work in Rajahmundry in 1909. ==Personal life==
