Hubert O. (Bert) Johnson, longtime stalwart of the Washington Map Society and indefatigable administrator of its Facebook group, died earlier this month of a heart attack. He was 73.

Bert and I only knew each other online, and that mostly via what we posted. In fact, we made a regular habit of stealing each other’s links. He’d share many of The Map Room’s posts on the WMS Facebook group, and many of my posts had their origins in something Bert posted on the WMS Facebook group.

An obituary and funeral details are still to come.
