Given the following context:

Army colonel and doctor Tom Owen returns home to Coalville, Pennsylvania, on leave. He learns from wealthy mine owner Dan Reasonover that his brother Floyd, a mine safety engineer killed in an explosion, had betrayed Dan's trust by purchasing substandard equipment and taking kickbacks. Floyd was also heavily in debt. Tom wants to pay Dan back, but Dan tells him to forget about the money.
Dan's daughter, the twice-divorced socialite Helen Curtis, meets Tom at a party and asks him for a date. She arranges for him to meet Dr. Homer Gleeson, who runs a fancy Pittsburgh clinic catering to wealthy women with imaginary health problems. Gleeson's associate has quit to open his own practice, so he offers Tom the vacancy. Knowing that Tom has vowed to pay his late brother's debts, Helen talks him into accepting, despite the fact that Tom enjoys the security his army career offers and knows his mother believes he should return to Coalville. As a nurse to assist him, Tom hires Joan Lasher, an attractive and idealistic young woman who plans to become a doctor herself.
Tom and Helen begin dating. Tom proposes marriage and she accepts. Her own father warns Tom that her wealth poisoned her first two marriages, but Tom remains adamant.
Lasher becomes disappointed that Tom treats wealthy society patients for minor ailments when he could be doing more good elsewhere. Dr. Jim Crowley, a former sergeant who was inspired by Tom's example to resume his medical studies, comes to Tom to ask for a job. Tom sends him to see Dr. Lester Scobee, who cares for the miners of Coalville and their families.

answer the following question:

What is the full name of the person who warns Tom Helen's  wealth poisoned her first two marriages? 

Dan Reasonover
