Dunhill increased his fortune (inherited) inventing and selling auto accessories after inheriting his father's successful harness business. So, he doesn't count. He simply leveraged leather, into auto parts, then a clothing business and finally added pipes and tobacco. Then his progeny, carrying on the tradition (the first lighter to be operated by one hand was invented by a brother or son or some such), leveraged that into millions selling off those businesses while they still had enormous value. I believe his chief business was making money. His tobacco/pipe businesses did that in spades.
I would guess he'd be quite proud of what the family is worth today. He didn't develop the pipe and tobacco empire because of any humanitarian drive. I doubt he had a real emotional attachment to various Dunhill owned businesses other than to make them successful. The clothing business catered to the rich, providing livery for drivers and such. The auto parts were also directed towards rich customers wanting to trick out their vehicles with things like clocks and cool mirrors. He knew to always go where the money was.
I think he'd be resting quite comfortably, knowing that his father's genius for making money filtered down, through him and on to the third and fourth generation of Dunhills. The Dunhill (dunhill) marques are still producing a lot of moneys. I doubt he would view the family name as sullied. Luxury items were what he sold throughout his life. Dunhill pipes were for those with money, not the working class. The tobaccos? Same target audience. There is a reason the first Dunhill tobacco products store was located in the most ritzy and wealthy part of London. The first American store was in New York, not Oshkosh.
