Born in Towson, Maryland on May 1, 1915, Jack went to Towson primary schools and the Boys Latin School in Baltimore. He received a B.S. degree from the University of Georgia in 1940. He later continued with post-graduate studies in engineering and geology at the Johns Hopkins University in Baltimore. At the University of Georgia, he met and married his wife of 52 years, Freddie Hill Loizeaux who passed away in 1992. They had four children, thirteen grandchildren, and thirteen great-grandchildren.

After working at other jobs, Mr. Loizeaux started his own company and developed new drilling and blasting techniques. He believed that buildings could be demolished safelywithout destroying the buildings around them and without injuring workers. Through experiments, he steadily moved toward the demolition techniques for which he was later known. He changed the company name from Burnbrae to Controlled Demolition Incorporated (CDI) in 1960, because that name better told what the company did. He preferred the term implosion (in which the the building fell in on itself) to explosion (where material from the building was thrown out from the building site), because he felt it more accurately described what happened: the toppling of high-rise buildings through the controlled use of explosives. The implosion of buildings became a universally accepted means of demolition. He received many national and international awards as a result of his explosives demolition innovations. His two sons, Mark and Doug, now head the company.

After he retired in 1980, Mr. Loizeaux lectured on many topics. He was committed to his family and friends and spent much of his free time in later years working with people who were not well. He was involved over the years with Young Life, Central and Mt. Washington Presbyterian Churches and the Loch Hill Chapel. He was also contributed to the work of his twin sister, Eleanor Johnson, who is a missionary in Burundi, Africa.

He was a sportsman who enjoyed sailing, biking and tennis and was an avid lacrosse fan. He died in 2000.
