 Schillings' association with Be Inc. began in 1990 when, as a developer of software for the Apple Macintosh, he visited the Apple Expo in Paris and met Jean-Louis Gassée.Gassée, who had just left Apple Computer to found Be, asked Schillings to become the second engineer at Be where he would work on the operating system for a new computer called the BeBox.Schillings accepted the offer and, starting in March 1991, developed a file system (now known as the Old Be File System or OFS) and an associated user-space database application (called Zookeeper) that indexed the metadata in the file system.
