Nyachae became a district commissioner in 1963. A few years later he became PC under both Kenyatta and Moi administrations. He would go on to become chief secretary in the civil service. Rumour has it as PC he would grab large tracts of land, then hand over about 60 to 70% to Kenyatta or Moi and keep the remainder.
Will always be remembered for telling Moi the truth - that the country is broke - when he was the finance minister in 99. He was promptly fired and replaced by a clueless and colourless Francis Masakhalia
A former classmate alitushow ati the late Nyachae was among the first people in Gusiiland to own a mirror and that he used to have locals come to his place to just look at themselves on the mirror and he would charge them for that. I don't know how true that was.
