No. 49 Cassidy Heirs
As a boy of 10, John Cassidy crossed the Atlantic from his native Ireland with nothing more than a pack on his back. He hauled bricks to make ends meet. Buying up Maine timberland at $2 and $3 an acre in the late 1800s, he founded Cassidy Timberlands, which is still based in Bangor with holdings throughout the Pine Tree State.
