After ordination, Father Jenemann taught philosophy, first in the 1962-63 academic year at what is now Loyola University in Baltimore, then at Wheeling (W.Va.) Jesuit University from 1963 to 1966.
He earned a doctorate in philosophy at the Pontifical Gregorian University in Rome in 1969, then returned to teach the subject until 1974 at Wheeling, where he was also rector of the Jesuit community from 1971 to 1974.
His 1974-80 term as chairman of the St. Joseph's philosophy department was followed by a 1980-83 term as director of the Faith and Justice Institute there.
Father Jenemann's top administrative assignment at St. Joseph's was to be both dean of students and vice president from 1982 to 1992.
The Jesuit priest moved a few blocks down City Avenue to become philosophy professor from 1982 to 1988 at St. Charles Borromeo Seminary, the incubator for parish priests of the Philadelphia Archdiocese.
From 1992 to 1996, he was assistant tertian director of the Maryland Province of Jesuits, which covers Philadelphia. Tertianship is defined as the third and last period in which a priest has a period of study and reflection before taking final vows.
From 1996 until last year, he continued to teach and counsel students at St. Joseph's.
Father Jenemann is survived by sisters Maryann Cornell and Barbara Mack.
