While digging on 666 5th ave, I found that it was built by the (((Tishman))) family in 1957. They also built 600 5th ave which is part of the rockefeller center. The family was also the general contractors that built the world trade center in 1973. They bought 666 back in 2000 and then sold it to Kushner in 2007. The 666 building, a Rockefeller building and the WTC…..maybe worth digging some more on the tishman's.
