John Siegenthaler, P.E., principal of Appropriate Designs in Holland Patent, New York, and longtime Plumbing & Mechanical and PM Engineer columnist, received a surprise recognition from Mark Olson, CEO of Caleffi North America, during the Carlson-Holohan ceremony. Siegenthaler was presented with the Legacy of Excellence Award for his writing contribution to idronics, a technical journal of design innovation now in its 32nd edition.

idronics has been a respected resource since 2007 for engineers, architects, wholesalers, contractors, educators and manufacturers in North America. idronics derives its roots from Idraulica, the Italian-inspired publication created by Caleffi founder Francesco Caleffi in 1991. "What could I do, as an Entrepreneur, in order to be able to help designers and installers, or those whom I consider my external collaborators?"

In 2007, Siegenthaler authored the first edition of idronics, Hydraulic Separation. Each journal is carefully planned about one year in advance of the edition's publication. Future and relevant topics are considered and discussed within Caleffi North America's "think tank:" a group of industry professionals both within and outside the company. Caleffi has proudly distributed nearly a half million copies of the popular journal series to date.

“I am very touched by the generosity and kindness extended by all of you over the years,” Siegenthaler said during the ceremony.
