Andrew Z. Muller born in Budapest in 1922 passed away on July 2, 2019. He loved drawing on canvas and online (Online Drawings) and learning on the Internet. He was very active on Facebook. Here are some of his online drawings.
He made this Voicethread in 2007 at the age of 85. The voicethread is was on his personal account which I can’t access at this time so I embedded it here because I couldn’t get a media file.
