As we say goodbye to the 8-4-4 system, there is no other Kenyan writer whose name we identify more with this education system (for good or bad) than Malkiat Singh. Singh came to Kenya in 1958 starting out as a primary and high school teacher before settling for writing books full-time in 1975. Although he sold his brand to Longhorn publishers in 2013, he still earns a royalty of 12% from every textbook you buy bearing his name. Not bad for retirement! And 100 books later – as they say, the rest is history.
