The Emery Oleochemicals company at 4900 Este Ave that sits on the Mill Creek has a very interesting history. Emery traces its origins to 1840, when Thomas Emery Sr. began converting lard discarded by meat producers in Cincinnati, Ohio, USA into candles and lamp oil.

The Soviets had already captured a rotating disk developed at Breslau by V-2 rocket engineer Richard Miethe. But Miethe had escaped capture by the Soviets in Breslau by flying out in a Messerschmitt Me 163 Komet. In April 1945 the 23rd Headquarters Special Troops, also known as the "Ghost Army" raided Peenemünde and captured the Horten brothers. Reimar and Walter Horten were German aircraft pilots. The Hortens designed the world's first jet-powered flying wing, the Horten Ho 229. The only surviving Ho 229 V3 is the only surviving Second World War-era German jet prototype still in existence and is on display in the main hall of the Steven F. Udvar-Hazy Center at [...]
