Jähnichen, a Roman Catholic, was born a few months before the outbreak of war in a small town in the mining region known sometimes as "Saxon Switzerland" near the frontier with Czechoslovakia. He attended secondary school in Grimma and Leipzig before moving on to study Agriculture at Leipzig between 1957 and 1963.

Rolf Jähnichen joined the Christian Democratic Union (East Germany) in 1981.^[2] (Unlike its west German counterpart, the East German CDU, as part of the country's National Front alliance was effectively controlled by the country's ruling SED party.)

The fall of the Berlin wall in November was the first of a series of events that by August 1990 had led to the end of East Germany as a stand-alone state and the reunification of Germany.^[2] During this period, between May and November 1990, Jähnichen served as the first freely elected council leader ("Landrat") in Borna district.^[1] Between February 1990 and September 1994 he served as district chairman of the CDU^[2] (the eastern and western pieces of which reunited in October 1990).

In October 1994 he was elected to the Saxony regional assembly (Landtag), representing a Leipzig district. He continued to sit as a member of the Landtag till the 2009 when he decided not to seek re-election in the September election. From 2000 he was also a member and chairman of his party's regional Senior Citizens' Committee.^[1]
