Ceremony in Philadelphia honors Aviation Pioneer Frank N. Piasecki

As 4 in the afternoon approached on Saturday April 17 in Philadelphia, a crowd began to gather on a blocked-off segment of Callowhill Street (between 19th and 20th Streets) to witness the dedication and unveiling of the city’s newest historical marker, placed at the site of helicopter builder and aeronautical pioneer Frank N. Piasecki’s first engineering office. The ceremonies started on schedule with a presentation of colors by a Marine Corps honor guard accompanied by members of Polish Veterans Post 12. Then former Philadelphia City Councilman Joseph Zazyczny greeted the assembly (of over 250 persons) in the name of the Polish Heritage Society of Philadelphia, an affiliate organization of the American Council for Polish Culture (ACPC). A moment of silence was observed to remember the victims of the airplane crash in which president Kaczynski and many prominent members of the Polish government died while on their way to Katyn. He was followed by Fred Piasecki, chairman of the board of Piasecki Aircraft who stood in for his brother John, the company’s president and CEO who was not able to attend, being in London while on a business trip when flights were canceled due to the volcano erupting in Iceland.

There were topical speeches by Senator Arlen Specter, a personal friend of Frank Piasecki; Lt. Gen. Michael Hough USMC; Flora Becker from the Pennsylvania Historical and Museum Commission (PHMC); and Phil Dunford, VP and General Manager of the Boeing Company. Peter J. Obst, who filed the application for the marker back in 2008 and then chaired the committee organizing the event, filled in for the absent City of Philadelphia representative. He read the proclamation issued by Mayor Michael A. Nutter which, after praising Mr. Piasecki for his activities that created a helicopter industry in the Philadelphia area, declared that this day was to be celebrated as Frank N. Piasecki Day in the city. While cameras from three TV stations (alerted by publicity chairman Walter Wojcik) took in the scene, Mrs. Vivian Piasecki, widow of the great engineer, started to unveil the sign. She pulled a cord attached to a cover held in place by velcro fastenings, it fell away and revealed the following words in yellow-gold letters on a blue background:



Aviation pioneer Piasecki developed and flew the 2nd helicopter in the US and the world’s 1st tandem rotor helicopter, initiating the 1st practical use of rotor-craft in the 1940s. His original company, started here, now a division of Boeing, is a world leader in helicopter production. In 1956, he founded Piasecki Aircraft Corp., continuing development of innovative advanced rotorcraft. Awarded the National Medal of Technology in 1986.

In conclusion there followed an eight-minute video presentation on a truck-sized electronic screen parked at the end of the street. It was an excerpt from "An Innovator’s Story" a film about the life and work of Frank Piasecki. When this concluded the crowd dispersed as the weather had turned rather cold and cloudy. Those who were to attend the post-dedication banquet boarded tourist trolleys which whisked them over to the Stotesbury Mansion, headquarters of the Catholic Philopatrian Literary Society, on Walnut Street.

At the banquet Deborah M. Majka, president of the ACPC introduced the important guests and speakers. Teresa N. Wojcik, president of the Polish Heritage Society, welcomed the participants. Fr. Leonard Lewandowski from St. Josaphat’s parish gave the invocation.

After a lovely dinner of shrimp or beef, under antique French chandeliers, several speakers took the podium to pay tribute to the accomplishments and legacy of Frank Piasecki. These were: Lt. Col. Paul Riegert USMC who praised Piasecki’s advanced helicopter designs in military application; Mike Walsh from the Office of the Secretary of Defense; Col. Andrzej Kopacki, Assistant Military Attache at the Polish Embassy; Prof. Marek Konarzewski, Minister Counselor for Science and Technology at the Polish Embassy, and Janusz Zastocki, Honorary President of Polonia Technica, the Polish engineers’ association in the United States. Prof. Konarzewski’s reference to the indomitable Polish spirit, evident both in cases of disaster, such as the recent airplane crash, and in the development of new inventions to benefit mankind, drew spontaneous applause from listeners. In conclusion Fred Piasecki thanked the guests for their participation and members of the audience gradually started for home.

As they left, guests were able to take home an event journal produced by Peter Obst which included a detailed biography of Frank N. Piasecki and many interesting photographs. So ended a very memorable banquet, that capped the ceremonies devoted to honoring the aviation pioneer. This marker is only the twelfth of those commemorating Polish-American contributions to the history of the Keystone State, interspersed among the two-thousand-plus that have been placed to-date along the roadways. Many more markers could still be created to recognize the impact that Polish immigrants and their children have had on this major industrial state. Those who are interested in the Pennsylvania Marker Program should look at the PHMC website:

Piasecki Scholarship. We would also like to convey our special appreciation to the Piasecki Family, and to Piasecki Aircraft Corporation, especially John Piasecki, President and CEO, for being the main sponsor of the marker and the street ceremony for which he provided not only funds but his personal time and attention. In addition we acknowledge Dr. Janusz Romanski, VP of Polonia Technica, for his assistance in publicizing the event and in fundraising for the Piasecki Scholarship Fund.
