It is true that chimneys draw a lot of air up the stack. Creating a negative pressure throughout the house. Letting cold air in any crack it can. You can call a HVAC technition to do a draft check when everything is running. There are genearlly enough cracks around doors windows and foundation that furnaces and gas water heaters don't need a special vent going to combustion. However, a fire place will use so much air that it will draw air in through the furnace and water heater stack. But, it won't be a fluid flow. It will pulsate. Drawing largeamounts of air up the fireplace and then drawing a brief amount of air out of the fireplace and into the room. You could install below ground or sidewall venting just for the fireplace. Since your house was built in 1935 it should not be very air tight. That is unless someone has systematically sealed the home. The best thing you can do is buy a small stove insert. There are covers you can place over the fireplace opening. But, a stove insert will create a negative presure within the stove and you can limit the amount of air going into the stove. Eliminating the negative presure in the house and stopping the rest of the rooms from getting cold. You will get more BTU's of heat from your wood and now burning wood will actually help reduce your gas bill.
