Leonardtown, MD – The St. Mary’s County Museum Division is happy to announce the opening of a new temporary exhibit now on display at the Piney Point Lighthouse Museum & Historic Park in Piney Point, MD.

Titled “America’s Greatest War Invention,” the temporary exhibit depicts the fascinating story of how a Maryland inventor’s discovery was developed into a novel method to intercept German military reports during World War I.

During the war, the Navy Department used a powerful undersea wireless device during military operations. These instruments, and system used to operate them, were developed by inventor James H. Rogers of Hyattsville, MD. Throughout his career, he filed more than fifty patents on devices related to the field of telegraphy, electrical lighting and telephonics. In 1908, he realized that electronic signal could be sent underground and through water, and from this came the Rogers System, which allowed radio receivers to hear clearly German military reports being transmitted from Europe. Further testing done along the shores of the Potomac River, while staying with his sister in Piney Point resulted in this, his greatest discovery.

“I would have never known about the Rogers System until one of the museum neighbors told me this fascinating story,” says April Havens, Site Manager of Piney Point Lighthouse Museum. “It turns out, the inventor James Rodgers was their relative who experimented with the system while staying with family at Mae Pine Cottage in Piney Point, during the 1900’s. History Matters!”

To learn the whole story about the Rogers System and how it helped shape the course of World War I, visit the exhibit at Piney Point Lighthouse Museum. This temporary exhibit runs until May 31, 2019. For more information call 301-994-1471.

We must also be able to pay employees(part-time and full-time), along with equipment, and website related things. We never want to make the Chronicle a “pay-wall” style news site.

To that end, we are looking to the community to offer donations. Whether it’s a one-time donation or you set up a reoccurring monthly donation. It is all appreciated. All donations at this time will be going to furthering the Chronicle through hiring individuals that have the same goals of providing fair, and unbiased news to the community. For now, donations will be going to a business PayPal account I have set-up for the Southern Maryland Chronicle, KDC Designs. All business transactions currently occur within this PayPal account. If you have any questions regarding this you can email me at

Thank you for all of your support and I hope to continue bringing Southern Maryland the best news possible for a very long time. — David M. Higgins II
