In the later part of 1882, Colonna left Europe for the United States and settled in New York City. He soon found employment with Louis C. Tiffany. He left Tiffany and took a position with the New York architect Bruce Price. It was through Price that Colonna was hired and began his new job at Barney & Smith Manufacturing Co. of Dayton, Ohio in September 1885. By 1897 Colonna was associated with Siegfried Bing and his celebrated Parisian store, Maison de l’Art Nouveau. In 1923 Colonna retired to Nice in southern France and he died there on October 14, 1948.

What were his major work?
The highlight of his career in Dayton was the publication of two small books containing some of his early projects. The first book was titled, Essay on Broom Corn and the second was Materiae Signa, Alchemistic Signs of Various Materials in Common Usage. Additionally, Colonna was initially tasked with designing extraordinary jewelry while working for Bing.

In the Art Nouveau pavilion at the 1900 Universal Exposition, Colonna won a silver medal for a reception room that also served as a music room; a music cabinet he designed is on display at the Renwick. This was a highlight for art nouveau and his most important work.
