My Quarter Century with Jan

This is the final and somewhat expanded version. The quality of the color photos of this version is poor as there is an upload limit on astro-ph. Much higher quality versions are available at http://space.mit.edu/~lewin/jvp.html . A bound hard copy with very high-resolution color photographs will be sent to you at request. Please send e-mail with your complete mailing address to lewin@mit.edu.
