South Deerfield, Massachusetts · 1884 – today

The Gass BuildersFour generations who raised, moved and rebuilt the houses of Deerfield

One South Deerfield family put up the village's blocks and stations, carried whole houses out of a valley about to be flooded, and rebuilt the landmarks of Old Deerfield into the museum street the world walks today. This is their story, house by house — drawn rather than photographed. Every sketch opens the folder of photographs behind it.

Who they were

Not one man. A dynasty.

Search the name William Gass and you will find it attached to a great many buildings across Franklin County. It is easy to assume that means one prolific man. It does not. Gass was a family firm in South Deerfield, Massachusetts, working from the 1900s into the 2000s — a father, his brothers, his sons and their sons, passing the trade down the line along with the name.

The best known of them, William Edward “Bill” Gass (1902–1986), remembered for a bow tie and suspenders, is described by Historic Deerfield as the restoration contractor who worked on many of the historic buildings in Deerfield. His father founded the firm. His son carried it into this century. The photographs on this site were printed in that son's darkroom.

The South Deerfield firmWilliam Gass Building Contractor Co. → William Edward Gass, Inc., Contractor-Designer (incorporated by 1957) → William E. Gass & Sons, Colonial Designers → Deerfield Home Building Center. The names are read straight off the sign in the 1962 photographs, the drawings at Historic Deerfield, and the letterheads in the family's papers.

The Greenfield firmSamuel's other son Thomas J. Gass (1876–c.1958) built schools, businesses and homes as Thomas J. Gass Co., General Contractors & Builders, 191 Main Street, Greenfield — later Greenfield Builder's Supply Co., run by his MIT-trained son Alfred. Two firms, one generation, one trade.

Which William? The family's own records credit the founder, William (1879–1952), with the restorations and the Quabbin house-moving. Bill's 1982 tapes, in his own voice, credit himself — and say his father's work was “modern construction, not restoration.” The likeliest reading is the simplest one: the father's firm, the son's craft. Where the record does not say which, this page says the firm.

The line of work

A century and a half of building

Dates below come from newspapers, library catalogues, the backs of photographs and the family's own records. Where a date is inferred it says so.

Old Deerfield · 1929 – 1966

Moved, raised, restored: the Street

The plaques on the famous houses along Old Deerfield's main street name each house's original eighteenth-century owner and build date. They do not say Gass, and they shouldn't: the family were not the colonial builders. They were the ones who came back two centuries later and saved the buildings — moving them, taking them down to the frame, rebuilding them into the museum village that Henry and Helen Flynt began assembling after the war.

From the Ashley House in 1948 to the Hoyt parsonage in 1966, Bill Gass was the Flynts' contractor and, as Henry Flynt put it in a 1961 letter, their designer too — “although he is not an architect.” Nearly forty years of their letters and invoices survive in the Historic Deerfield library, filed house by house. Some of these houses are not standing where they were born. They are standing where Bill Gass put them.

How to read the tags. Documented means a letter, a catalogue record, a published account or Bill's own voice on tape. Family record means the family's captions and binders. Match to confirm means a photograph in the box that looks like this house — a hypothesis for the historian, not a fact.

Saved from the water

From the ground up

Before the restorations, simply the builders you called

Blocks, stations, stores, churches and a great many houses in and around South Deerfield — the everyday work of a village contractor, 1908 to the 1990s.

1961 – 1978

Deerfield doorways, far from Deerfield

By the 1960s the firm was shipping Deerfield to the rest of the country. Flynt recommended Bill to clients in Connecticut who wanted “a modern colonial green” of reproduction houses; the firm's stock plans — the D-series — went out to Kansas, Michigan, Florida and Wisconsin; and its trucks and crates went to Ohio, Georgia, New York and the Virgin Islands. The proof is on the backs of the prints.

The family's own places

Two houses on Graves Street, a camp on a lake, and the shop where the doors, the cabinets and — in the darkroom at the back — the photographs were made.

Field guide

How to spot a Gass building

The records are incomplete. The buildings are not. Three habits give the family away.

And the windows. In December 1961 Henry Flynt wrote to “Dear Bill” because out-of-town visitors kept questioning the twelve-over-twelve sash on the 1824 Wright House, and he wanted the references behind the decision. Small panes, many of them, on houses that might not have had them: a Gass habit that the museum's own curators still discuss.

Help us name them

Seventy-eight houses, lettered A to BV, waiting for a name

Pépère kept the photographs of every house together in one box, but wrote on almost none of them. Each house is now its own folder, lettered in the order he kept them, with its interiors beside it. If you live in one of these houses, restored one, or recognise a doorway, a fireplace or a hillside — that knowledge is worth as much as the photograph.
