Hartmannganj mission which was established in 1968, in Bahmalpur, Phaphamau had been engaged in the field of social work and health and hygiene to help the poor of Bahmalpur and surrounding villages. To add to its activities of helping the poor a primary School in Hindi medium with the name Hartmann Primary School was established by late Rev.

The School catered to the educational needs of the poor in the Trans - Ganga area. The School obtained recognition from U.P. board in July 1986. The school was closed in the year 2007 for some unavoidable reasons. But Most Rev. Isidore Fernandes, then Bishop of Allahabad, with a desire to continue to help the poor children of the area in education decided to re-establish the school.
