December 3, 1915. He received his schooling in Germany, followed by some 

 years of invaluable practical training and experience. 



In 1869 he came to the United States, and with characteristic energy 

 immediately developed ideas which the wider field of this country afforded. 



He was among the first to realize that steam machinery was to use 

 higher pressures, and his first patents were issued to cover what are today 

 known throughout the world as Katzenstein's Metallic Packings. He was 

 the recognized pioneer and leader in this field and patented a large number 

 of devices covering improvements in this art. Other patents held by him 

 covered automatically operated bulkhead or compartment doors for ships 

 or mines, lifeboat appliances, etc. He also built up an extensive business 

 for the manufacture and repair of machinery. 



He was a member of this Society, the American Society of Naval En- 

 gineers, the Railroad Club, the Technischer Verein, and of many charitable 

 organizations. 



In a long and honorable business career he established an enviable repu- 

 tation for integrity and ability, and his lovable personality brought him a 

 host of friends. 



He was of a modest and retiring disposition. He was a high-minded 

 citizen. In charity without display he gave generously to the needy. His 

 faith in God was steadfast, and as a husband and father he was gentle 

 and noble.
