Final answer:
The question why Andrew Carnegie extended his trip abroad is not explicitly addressed, but Carnegie's actions during his trips, such as learning about the Bessemer Process, significantly influenced his success in the steel industry. Later in life, Carnegie's focus shifted to philanthropy, guided by his belief in the social responsibilities of the wealthy.
Step-by-step explanation:
The question regarding why Andrew Carnegie extended his trip abroad isn't directly addressed in the provided reference material. However, through Carnegie's ambitious nature and keen business acumen, it is known that he constantly sought new methods and technologies to advance his business interests, particularly in the steel industry.
During a trip to England, he observed the Bessemer Process, a way to produce stronger and cheaper steel, which he later brought back to Pittsburgh and applied to his own Carnegie Steel Factory.
This innovation, among other shrewd business practices like vertical integration and expansion during economic recessions, allowed him to dominate the U.S. steel market.
Late in his life, Carnegie's philanthropic endeavors became his primary focus. His famous essay, The Gospel of Wealth, espoused the belief that wealthy industrialists, like himself, owed a duty to society.
Thus, he became known for his extensive charitable contributions to libraries, schools, and institutions of higher education, becoming a celebrated philanthropist.
