happy world vegetarian day!

wishing "happy world vegetarian day" to all of my fellow vegans in DC and around the world. (and hoping that everyone in Puerto Rico, the Virgin Islands, Dominica and around the world are able to eat something today, tomorrow and all the following days.)

Recently, I found on eBay a Seventh Day Adventist Cookbook that was published in 1968 by the Review and Herald Publishing Association (the publishing arm of the Seventh Day Adventist Church) located in DC.  

Do you know Emmy K. Schwarz, the former owner of this cookbook? Does anyone remember using this cookbook or having it in your kitchen?

I'm very interested in the history of vegetarianism and veganism in DC in 1968. I know that the Glut Food Co-op started in a D.C. church, c1968. 

What do you remember about the veg*n scene in 1968?
