In this house on Hawthorne Street, the Wright brothers, then in their twenties, developed their interest in aeronautical science as Wilbur and Orville debated ideas for a flying machine around the dining room table. Five adults lived here during those years. After their mother died of tuberculosis in 1889, when the brothers were teenagers, Milton Wright led a family of young adults that placed a high value on family unity. The four Wrights who lived here trusted, depended on, and defended one another to an extraordinary degree rather than seeking help from outsiders. The house was comfortable for its day, filled with Victorian furniture, books, and visitors, and the brothers' spirited dinner table discussions here led to the solutions they needed to invent the airplane. Bishop Milton Wright, who lived here, was an editor, theology professor, and conservative minister of the United Brethren in Christ (Old Constitution). Wilbur Wright, the third of seven children, died here of typhoid fever in 1912. Orville Wright, the sixth of seven children, never married, and neither did Wilbur. Katharine Wright, the youngest of seven children, was 29 years old when her two brothers first flew in 1903. Carrie Kayler Grumbach kept house for the Wright family from 1900 to 1948.
