Jacques is the president of the Schnee Dust Company. Keeping his company in good graces as well as flush are prominent goals.
Jacques married into the Schnee family, becoming Nicholas' son-in-law. When Nicholas' health began to fail Jacques managed to convince his father-in-law that he was the perfect man to take over the Schnee Dust Company.
Not much is known about their relationship, but judging by the family portrait in "Remembrance", they have an unhappy marriage, which has driven his wife to drink. When Whitley informs Weiss that Jacques was yelling at someone in his office, Weiss immediately assumes that it is her mother, implying that the two fight often.
Jacques has a very apparent strained relationship with his second daughter, both hold much contempt towards each other as Weiss' preference to independent thinking clashes with his controlling and overbearing nature. After Weiss attended Beacon against his wishes and she did not respond to his phone calls he cut her off financially. Several months after Weiss returns to her family home, Jacques subtly coerces her into singing at a charity concert. Jacques has made it clear that he plans to use Weiss' presence at the Battle of Beacon to improve the company and family image.
During the Vale charity event, Jacques wants Weiss to stay by his side at all times, even grabbing her by the arm when she attempts to move away. He shows a deep disappointment in Weiss after she publicly loses her temper during the soiree and unintentionally summons a Boarbatusk that attacks a guest. In "Punished", Jacques and Weiss argue. He slaps her for questioning his right to the Schnee name and announces that he intends to transfer the inheritance of the Schnee Dust Company from Weiss to Whitley.
He and Winter have a strained relationship similar to that of his other daughter. According to Winter, he was not pleased by her joining the Atlesian Military when she graduated from Atlas. In "Punished", Jacques states that he considers her to have "run off" and implies that he and Winter are not on the same side.
Whitley is Jacques' son. It is uncertain if his relationship with Whitley is the same as how he treats his daughters, although the photo on his desk seems to imply Whitley to be his favorite. Evidence of this is seen at the charity event, as Whitley is always by his father's side, whereas Winter and Jacques' wife are nowhere to be seen. In "Punished", Jacques goes as far as transferring the inheritance of the Schnee Dust Company from Weiss to Whitley.
Although Jacques states him to be a trustful friend and ally of his family, he appears displeased with the General during the events of Volume 4, specifically in regards to his "role" in the fall of Beacon and the recently imposed Dust embargo. Jacques also resents James, believing he "stole" Winter from him.
As mentioned by Weiss, Jacques is known to have been under strain and embitterment by the SDC's bloody conflict with the White Fang. The White Fang's reasoning for targeting the SDC is for the questionable practices that occur under Jacques' leadership. Jacques is shown to shrug it off, claiming he pays Faunus miners the same wages as humans.
