Margaret Carnegie Miller has been in the limelight for being the heiress to the Carnegie fortune. She was known around the world as the only child of industrialist and philanthropist Andrew Carnegie and Louise Whitfield.
Margaret Carnegie Miller’s Family
Margaret Carnegie Miller was born on 30 March 1897, in Manhattan, New York, United States, to the industrialist and philanthropist, Andrew Carnegie and Louise Whitfield. She was named after her paternal grandmother. Her father, Andrew Carnegie was born on November 25, 1835, to Margaret Morrison Carnegie and William Carnegie in Dunfermline, Scotland, in a typical weaver’s cottage with only one main room.
He did not want to marry during his mother’s lifetime, instead choosing to take care of her in her illness towards the end of her life. After she died in 1886, the 51-year-old Andrew married Louise, who was 21 years his junior, on April 22, 1887. Louise Whitfield was born on March 7, 1857, in the Chelsea neighborhood of New York City to John D. Whitfield, a prosperous New York City textile merchant, and Fannie Davis. Ten years after marriage, in 1897, Louise gave birth to the couple’s only child, Margaret.
On April 22, 1919, 4 months before her father’s death, Margaret married Roswell Miller Jr. at the Carnegie family home at 2 East 91st Street on the Upper East Side. They had four children: Roswell Miller III, Louise Carnegie Miller, Barbara Miller, and Margaret Morrison Miller. Their marriage ended in divorce in 1953. Margaret died on April 11, 1990, at her home in Fairfield, Connecticut, at the age of 93.
Margaret Carnegie Miller’s Net Worth
Margaret Carnegie Miller was born with a silver spoon. Her father, Andrew Carnegie, was the mastermind behind Carnegie Steel, which became one of the largest steel manufacturing companies in the world. The Carnegie family is legendary in the realm of wealth and philanthropy. With such an impressive family business, it’s no wonder Margaret was sitting on a mountain of wealth. The estimated present-day value of Andrew Carnegie’s fortune, according to the Carnegie Corporation of New York is around $309 billion.
Andrew led the expansion of the American steel industry in the late 19th century and became one of the richest Americans in history. He became a leading philanthropist in the United States, Great Britain, and the British Empire. During the last 18 years of his life, he gave away around $350 million (roughly $5.9 billion in 2022), almost 90 percent of his fortune, to charities, foundations and universities. His 1889 article proclaiming “The Gospel of Wealth” called on the rich to use their wealth to improve society, expressed support for progressive taxation and an estate tax, and stimulated a wave of philanthropy. After Andrew’s death, Margaret became the sole heiress of his fortunes. She was a trustee of the Carnegie Corporation of New York, the grant-making foundation established by her father.
