Salon - August : Entrepreneurs and Monopolies in the 19th Century

Chris B is in from California to present this fascinating topic. (I hope railroads are in there somewhere.)
Please note this is the August salon, the July salon is on the 26th. I know they are only two weeks apart but our distinguished presenters are in great demand.

Please also note the start time is later than usual. Furthermore the time and location are subject to change. It will be Sunday afternoon in Boston but within those parameters details may change.
