Princess Marconi Visits CMMC for Grand Opening of New Education Center
Princess Marconi at CMMC (2006)

Princess Elettra Marconi, daughter of Guglielmo Marconi, will be the honored guest for the grand opening of the new Chatham Marconi Maritime Center's Education Center, the featured event of the June 20th-22nd Chatham History Weekend 2014 festivities at the site on Ryder's Cove in North Chatham.

The weekend also includes free admission to the site's Marconi-RCA Wireless Museum and the exhibits in the new Education Center. On Saturday afternoon, Calvin D. Trowbridge, Jr, author of Marconi: Father of Wireless, Grandfather of Radio, Great-Grandfather of the Cell Phone, The Story of the Race to Control Long-Distance Wireless, will discuss the inventor's life and impact on society.

The princess' visit comes during the centennial celebration of her father's company constructing the campus on Orleans Road (at Old Comers Road) which, under the ownership of the Radio Corporation of America (RCA), became one of the largest ship-to-shore wireless-communications stations on the east coast. [Click here to see video of Princess Marconi talking about her father. ]

The celebration kicks off June 20th with an invitation-only event in the Education Center, the renovated building which was once the Hotel Nautilus and then a residence for site staffers. Local, regional and state luminaries will join CMMC directors at 10 a.m. Saturday, June 21st for the ribbon cutting officially opening the "hotel's" doors to the public.

In addition to being the home of CMMC's education efforts, which are centered around STEM programs, it will house administrative offices, public-meeting space and exhibits complementing those in the adjacent museum.

The museum presents an interactive history of wireless communications, including exhibits about Marconi's ground-breaking achievements here and across the globe, a history of the activities at this facility (including its use by the U.S. Navy during World War II) and the Marconi company's part in rescuing survivors of the Titanic sinking.

The displays in the Education Center, which will change and evolve over time, focus on the present and future impact of wireless communications including one detailing tracking sharks with satellites and another on real-time ship tracking, again through wireless means.
