He lived for several years in Kuala Lumpur.
Dr. Semegen’s writings were published in a range of publications, including Encyclopedia Britannica, Encyclopedia of Materials Science and Engineering, Encyclopedia of Physical Science and Technology, Vanderbilt Rubber Handbook, Oxford Encyclopedia of Materials and Engineering and Rubber Technology and Rubber Age. He was also a frequent lecturer at universities throughout the United States and Canada, as well as Mexico, South America, Malaysia, Japan, Europe and the Soviet Union.
He was preceded in death by his wife, Jane Schmiedel Semegen, who died in 1985, his second wife Beverly Heisler Semegen, who died in 2010, and his son Patrick.
