Anne Frank in her 15 APR 1944 entry writes this:
" Peter forgot to unbolt the front door. As a result, Mr Kugler and the warehouse
" employees couldn't get in. He went to Keg's, smashed in our office kitchen
" window and got in that way. The windows in the Annex were open, and the
"Keg people saw that too."
Who were the "Keg people"?
