Pascal Rougon

He is the middle son of Pierre and Félicité but nothing like his brothers Eugene and Aristide. He studied as a doctor in Paris and then returned by preference to Plassans. He looked to help the less well off and was seen by Silvère Mouret working amongst the insurgents. To keep his mother happy he sometimes attended the yellow drawing room but had no interest in the discussions and amused himself by comparing the people there to various animals.
Although nobody in Plassans knew, he was well regarded in the world of science.
In La Curée he is referred to as an unmarried doctor in love with science who made his home in Plassans. He had several times offered to look after his niece (Clotilde), and she came to live with him on the death of her mother in 1854.
