Dr. Reinaldo Irizarry, Sr., PhD, is an accomplished author with a passion for exploring the mysteries of the universe. Born on February 9th, 1944, in Puerto Rico, he moved to the United States in 1950, where he received part of his primary education in New York City. In 1962, Dr. Irizarry joined the military and served in Vietnam from 1966 to 1967. The profound experience of witnessing the sacrifices of his comrades left him with a lasting sense of guilt for those friends who never made it back. Upon his return home, Dr. Irizarry embarked on a new chapter in his life. He met and married a wonderful woman, and together they raised beautiful children. He considers himself blessed and attributes his gratitude to the goodness of God, who has always been by his side.

Dr. Irizarry has authored six books before his latest work, Are We Humans or Aliens? His previous works include Home from Nam, A Touch of Blue, One Man's Opinion, and World War III, and more. In his latest book, My Friend Duke he shares heartfelt reflections on his 15-year companionship with his beloved pet dog Duke.
