The Highline Historical Society will be hosting a “Now and Then” presentation by popular documentary photographers/historians/authors Paul Dorpat and Jean Sherrard on Saturday, Jan. 24, starting at 2 p.m. at SeaTac City Hall.

Dorpat has written his popular column for The Seattle Times’ Sunday magazine since 1982, and has published a dozen books, including three volumes of regional now-and-then photographic comparisons drawn from his column, and “Building Washington,” an illustrated encyclopedic study of the state’s historical development that he co-authored with Genevieve McCoy. Dorpat’s collaboration with Jean Sherrard began in 1999 with the production of bumberchronicles, a video history of Bumbershoot, for KCTS-9. In 2004, Sherrard began helping with the “now” photographs for Dorpat’s column.

This program is free to Highline Historical Society members who can show their current membership card. An $8 donation is requested of all others.

SeaTac City Hall is located at 4800 S. 188th Street in SeaTac.

Parking is free.
