Lothar had been born in 1630, the third son of that family. None of those boys had attended school. They had been raised within the household, and educated by tutors—some hired, others simply members of the family who possessed knowledge, and a willingness to impart it. Egon von Hacklheber, a man of exceptional erudition, who had traveled widely, had devoted an hour or two each day to educating the three von Hacklheber boys. Lothar had been his brightest pupil; for, being the youngest, he had to work hardest to keep up with his brothers.
