From Wikipedia, the free encyclopedia

I am a retired organic chemist with a PhD from Johns Hopkins University in Baltimore, Maryland, USA. My work experience included industrial hygiene and safety, investigation and remediation of hazardous industrial waste sites, and measurement and destruction of chemical warfare agents, especially VX. My previous interests were orchid growing and orchid taxonomy, and the postal history of the Prussian province of Pomerania (Pommern) before its split at the Oder-Neisse line between Germany and Poland. My current interests are birding (twitching) and avian taxonomy, astronomy, and Old Testament and New Testament Bible study.
