Andrew Morton is the lead maintainer for the Linux 2.6 kernel series. Andrew, with Linus, is the final arbitrator of which patches are accepted into the stable kernel series.
It has been suggested Andrew Morton is one of the things that the kernel developers have gotten right in the last few years. A graduate of the University of New South Wales in Electrical Engineering, Andrew was the creator of the Applix 1616, a DIY computer kit released in the late 80s.
Since then Andrew has worked in the Software and Hardware engineering fields to some acclaim, quickly becoming prominent when he got involved with Linux Kernel Development. Andrew is now employed by OSDL with Linus Torvalds and Andrew Tridgell.
