Henry Petroski is a professor of engineering and history so perhaps it's not surprising that when he and his wife bought a house on the Kennebec River in Arrowsic, he got interested in its history.
The house was built more than sixty years ago and while its architecture is nothing special, its craftsmanship is.
Henry Petroski has written a book about it called "The House with Sixteen Handmade Doors."
His wife Catherine took the photos for the book, which is sort of a detective story, one that digs into the history of how this house came to be what it is.
