Niels Harrit, PhD, was born in 1945. He has served as associate professor of chemistry at the University of Copenhagen 1971 – 2009 and published more than 60 peer-reviewed papers. Since 2007 he has been actively involved in the global movement for 9/11 truth, demanding an independent investigation of the terror attacks on September 11th, 2001. He was the leading author of a scientific paper, published in April 2009, describing the findings of active thermitic material in the dust from the collapses of the three (!) skyscrapers of the World Trade Center. He was a member of the 9/11 Consensus Panel. Over the years, Dr. Harrit has given 400 presentations on the collapses of the World Trade Center skyscrapers in Denmark, Sweden, Norway, Germany, Holland, France, Switzerland, Spain, United Kingdom, Canada, USA, China, Australia, Russia and Iceland. Since 2020 this activity has been extended to cover the false narratives of the so-called Covid-19 pandemic from a scientific perspective.
