Harry Fowler (Remembrance of the Daleks)
From Tardis Wiki, the free Doctor Who reference
Harry was the owner of a café in Shoreditch. He chats with the Doctor, when he arrives in the cafe. When Ace came into the cafe, she didn't know how to get his attention, and Mike Smith helped her. He later was in hopsital off-set when his wife was giving birth to twins. He left the cafe in the care of John.
