reasons we are so excited to have jonathan here tonight, is that the library is the proud home of the jonas salk personal archive. i really appreciate the generosity of his three sons. jonathan, peter and darrell for helping us with the archive of nearly a thousand boxes of jonas's personal and professional writings. i understand that there are many stories including of course, the founding of the vaccine, developing of the vaccine and opening of the salk institute for biological studies. i'm happy to announce we committed to digitizing a set of audio recordings made and has been in the archive for quite some time. i understand some recordings actually have not been heard for well over 50 years. and i think that is a great development and we really look forward to getting them digitized and funny what's on them and making them publicly available. before i invite jonathan to the podium, i would like to express my appreciation to library staff that help us coordinate the event. to particularly -- has been a steward, linda, thank you! and really helped pull this together. with that, please join me
