Bricks, Masonry, Asphalt and Concrete - Cutting a hole in a brick wall

My brother recently moved into a ranch house with a full brick exterior. It's about 50 years old. The laundry area is off the kitchen at the rear of the house. There was never any dryer vent outlet built into the house...the owner just stuck the vent hose through an open window next to the dryer whenever she used it. My brother wants to cut an opening in the brick wall to install a permanent vent opening, but we don't know just how to go about it properly without damaging the wall or weakening the overall integrity of the structure. Any suggestions?

If you chisel out the mortar around one brick and remove it, a standard dryer vent will fit through. You can cut the brick in two and replace part of it to fill the remaining void.
