Henry de Groh III

Hi! I'm an engineer and scientist, now retired after 37 years at NASA. I was having trouble starting my wood burning stove, along with smoke coming into my house. Since I knew it was because the stovepipe was full of cold, heavy air, and didn't like available products to fix it, I designed The Draft Helper to solve these problems. 

I am also a craftsman and musician and build audio projects like loudspeakers and boomboxes. Over time, I have so many beautiful builds I don't have room for them. So, I also sell speakers, mostly to make room for my next speaker creation. My speaker builds almost always use used, reclaimed, or recycled materials.
