He later worked with the District of Columbia government buildings, and established a longstanding private practice in Baltimore, Maryland.

"Henry Adams," the memorial article said, was a good citizen, a just man, a capable engineer, full of charity, and died beloved by all who knew him.

Henry Adams received his early education in Germany but came to the United States to seek a wider field of activity in 1880.

He was appointed Chief Engineer of the Office of the supervising Architect of the United States Government in Washington, DC which was a position he filled with distinction for 18 years.

Upon his resignation, he opened business office in Baltimore in 1898; the company became Henry Adams, LLC which still exists today in Towson, Maryland.
