Towers & Turrets: Victorian Mansions on the Main Line, 1870–1905

presented by Jeff Groff

The former "Rostrevor" in Haverford, Pa., built in 1884

This talk examines the great Victorian era mansions on Philadelphia's Main Line. It focuses on those built for the Baldwin Locomotive Works partners, Pennsylvania Railroad officers, and leading industrialists and manufacturers. Architects featured include Furness & Evans, T.P. Chandler, Wilson Brothers, William L. Price, and G.W. & W.D. Hewitt.

For sixteen years he was Executive Director of Wyck Historic House and Garden in the Germantown section of Philadelphia. He directed the Osterville Historical Society on Cape Cod, and early in his career was Registrar/Asst. Curator at the Philadelphia Maritime Museum (now Independence Seaport). A graduate of Bates College where he majored in history, he holds an MA from the Winterthur Program in Early American Culture of the University of Delaware.

For over forty-five years he has studied and lectured on American country houses and gardens, particularly those of Philadelphia's "Main Line" and surrounding areas, with an emphasis on country life and sports, and gentleman farming.

He served as co-curator of Winterthur's very successful exhibitions "Costumes of Downton Abbey" and "Costuming The Crown."

2023 Member Excursion

On Saturday, 10 June 2023, all current Society members were invited to join us for our Annual Member Excursion, which this year took us to The Mill at Anselma in Chester Springs.

Nestled along the Pickering Creek in Chester Springs, Pennsylvania, the Mill at Anselma is an extraordinary historic site demonstrating over 250 years of Chester County's industrial history. The 22-acre property and surviving historical buildings demonstrate a heritage engineered to last. The Mill retains its original Colonial-Era power train, as well as multiple layers of industrial equipment ranging from the late 1700s to the mid 1900s. A National Historic Landmark since 2005; an operational Mill before the United States of America; an independent, non-profit historic site today.

The workings of the Mill at Anselma in Chester Springs are a valuable window into how a colonial era grist mill was built and functioned. We were be able to see the Mill's water wheel in operation during our tour, as well as learning about the history and context of farming, milling, and shipping Pennsylvania flour around the world.

The staff of the Mill provided us with a guided tour, after which we enjoyed some light refreshments and an opportunity to converse. As with other recent excursions, we were open to being joined by members of the King of Prussia Historical Society.

Important — RSVP

To assist us with planning for the event, we asked that participants let us know that they were planning to attend.

The Society covered admission fees for all pre-registered members. Others were advised to expect to pay the regular admission fee ($10 for adults, $5 for seniors (age 62 and over) and youth (age 4–14).

Our tour started at 1 PM. Appropriate health and saftey precautions were expected.

Chester Springs, PA 19425

Our Most Recent Meeting

This Society meeting was held at 2:00 p.m. on Sunday April 21, 2024
in-person at Tredyffrin Public Libary in Strafford, Pa.

Warwick's Buried Cannon

presented by Daniel A. Graham

One of the cannon unearthed at Warwick Furnace in 2022.

One of the enduring legends about Warwick Furnace is the Revolutionary War story about the buried cannon and the bell that was rung to call the neighbors to come and help bury them.

During the 1777 British advance on Philadelphia, cannon cast at Warwick were buried in the fields next to French Creek, and the fields then flooded, to keep the cannon from falling into British hands. At the last moment, the British turned east to invade Philadelphia and did not molest the furnace.

The buried cannon, all 18-pounders, were never dug up and laid there for almost 100 years—unmentioned but not completely forgotten. Seven were dug up in 1875; five more were found in 1895, one in 1903, and four in 2022. This is the story of how they were made, hidden and found once again.

Daniel A. Graham is an early Pennsylvania iron researcher and a Potts and Rutter family historian. He has written more than 60 articles, papers and books on the iron industry in Berks, Chester, and Montgomery Counties, and on Pottstown, Valley Forge and the Revolutionary War. He holds a B.S. from West Virginia University and an MPA from George Washington University. He is retired and lives in Montrose, Susquehanna County, Pennsylvania.



Society Special Events

"Behind the Doors"

The original Tredyffrin Easttown History Club occasionally held meetings at the various historic Inns in the area, as noted in this quote from an article about the history of the Club found in the October 1965 issue of the Quarterly (v.13 no.4, pg. 80):

On March 7, 1939 the first annual Banquet was held at the Windmill Tea Room (the General Jackson Inn) at Paoli. Originally the Club had these affairs at some historic inn. To date the following Inns have played host: The King of Prussia (once), Ye Old Bull Tavern (three times), General Warren (twice), Wayside Inn (General Jackson) (Five times).

Starting in 2013 this tradition was revived. So far we have visited two inns, both with tours and history presentations followed by a delicious five course food and wine pairing dinner. Both events were a great success and we look forward to more in the future. For more information, view the individual invitations for these events:

A portion of the proceeds from these events benefits the Tredyffrin Easttown Historical Society.

TEHS exhibits at local public libraries

TEHS display case at Tredyffrin Public Library

Did you know? The TEHS maintains a display case of local history materials in the Local History Room at the Tredyffrin Public Library.

The current exhibit highlights Herb Fry's book collection.

C. Herbert Fry was an active contributing member and officer of the Tredyffrin Easttown Historical Society for over thirty years. Herb gave numerous talks and wrote over two dozen local history articles for the Society's History Quarterly periodical. He and his late wife Barbara amassed a collection of historical photographs, books, articles and other research materials that filled two closets. Following his death in July 2018, all of his local history materials came to the Society. One of his special interests was Valley Forge, and his books on the subject numbered over forty. Eight of these are displayed in this case.


Another example is this book by Frank Resavy & Tom McNichol.

TEHS display case at Easttown Library & Information Center

During the month of April 2018, a display case in the main entry hall of the Easttown Library in Berwyn contained an exhibit featuring nine historic photos of Berwyn with intriguing captions, testing the viewer's knowledge of the area.



S. Paul Teamer Awards

As we passed the milestone of our 75th anniversary as an organization in 2012, it seemed fitting to establish a new annual award to recognize the especially significant contributions made by some of our members over the years. In considering what name this award should have we decided to reach back to the very beginning of what was then The Tredyffrin Easttown History Club and to founder and first president S. Paul Teamer. It is certainly worthwhile to look back at those first few volumes of the Quarterly and rediscover the noteworthy articles written by Teamer and his colleague Franklin L. Burns, among others, who set a high standard for those who followed.
