Sacolton inquired, "If CTR wasn't a Freemason - why is he buried at the Greater Pittsburgh Masonic Center?"
C. T. Russell is NOT buried at the Greater Pittsburgh Masonic Center, he was buried in the Rosemont United Cemetery in 1916. This was in harmony with the instructions he left, which said, in part, "I desire to be buried in the plot of ground owned by our Society, in the Rosemont United Cemetery..."
The Watchtower Pyramid Memorial is NOT Russell's headstone, so CTR is not UNDER the pyramid, as some have claimed. It marks the center of the plot owned by the WTB&TS, a plot that contains the remains of other people who lived and worked at Bethel. This is the first of at least three burial plots that have been used by the WTB&TS. There is one on Staten Island in NYC, and one in upstate NY at the Bethel Farm (I don't recall the name of the town).
If one takes the time to investigate, one learns that the Greater Pittsburgh Masonic Center had its corner stone laid in 1995, 79 years after CTR died.
Then again, if there was a Starbucks Coffee Shop across the street from CTR's grave, I'm sure there are some people who would insist that CTR was a barista specializing in vente espressos con panna with a sprinkle of nutmeg.
