From the obituary for Phil Chess, who was born Fiszel Czyz in 1927 in Motal, which was in Poland at the time but is now in Belarus.
Chess Records recorded Chuck Berry and Bo Diddley and many others.
Over the years, the Chess brothers were accused more than once of taking financial advantage of their artists, and there were lawsuits, usually settled confidentially. Some Chess artists said their compensation was more often like an allowance than like a salary. But there were many instances of apparently genuine friendship: Chuck Berry sometimes stayed overnight at Phil’s house.....Key quote from Phil Chess: "I didn’t know what I was doing."
