Special to College Values Online

Since Mississippi College opened its doors to women in 1813, allowing them to pursue college degrees in the US for the first time, women have been shattering glass ceilings and preconceived notions with tremendous force. It hasn’t been an easy journey, navigating first the halls of academia and then on to the corporate ladder; women have been striving to reach the very top. And they have succeeded! It has been a long, and sometimes bitter, fight.

In 1909, 15,000 women marched the streets of New York City. What did they want? Shorter hours,
better pay, the right to vote, and the end to the oppression of women and the vast inequality between
them and men. A decade later, they were finally given the right for their voices to be heard at the ballot
box, but the fight for true and complete equality is ongoing, even a century later.

March 8th is the date known as International Women’s Day thanks to a strike by Russia’s women,
demanding “Bread and Peace” as millions of Russian men died during World War I. They continued to
strike for four days before Vladimir Lenin relented and declared February 23 (according to the Russian
used Julian calendar while the West marked the day March 8th according to the Gregorian calendar).
Over the next 60 years, the day was mostly celebrated in socialist and communist countries. But in
1975, the United Nations declared the day International Women’s Day and made it a U.N. holiday two
years later. For the next 25 years, the day began to lose steam in terms of popularity and recognition.
However, in 2001, a new website was launched. This site has been given much of the credit for the interest in reviving the celebration of this important day.

Today, while the struggle for equality continues, there are positives to see in their fight. Sadly, the
E.R.A, the Equal Rights Amendment has never passed here in the United States, their position in the
boardroom has never been stronger. A 2009 study showed that of the 2,000 top-performing companies,
only 29, or about 1.5%, had a woman as their CEO. Today, approximately 8% of all companies have a
woman at the top of the corporate ladder. It’s not enough, but at least it’s a trend in the right direction.


This list of the 30 Top Female CEOs used a simple source to determine its order. Every year, Fortune
magazine publishes the Fortune 500, a list of the top 500 corporations worldwide as measured by
revenue. The first version was published in 1955. Originally, the list only included companies that got
their revenues from manufacturing, mining, and energy exploration. It wasn’t until 1972 when the first
company led by a female CEO appeared on the list. The Washington Post Co., led by Katharine Graham,
made the list at number 478 in 1972. Between 1972 and 1994, the list included female-led companies
50 times on its lists. Graham, and the Post, appeared on every list until 1991, when she was succeeded
as CEO by her son, Donald.

In 1995, the Fortune Magazine list changed. Previously, the magazine had separate lists for industrial
companies and non-industrial/service companies, but the new list combined the two. With this new
format, there were no companies led by a woman on their new list, though there were companies in the
bottom 500 with a female CEO. Women returned to the top half of the list the following year with Marion
O. Sandler, CEO of Golden West Financial Corp, making the chart at 491. She and the company had
appeared on various lists between 1974 and 1994.

In its history, more than 1,800 different companies have made the Fortune 500 list. While the number
of companies led by females has varied over the last 25 years, the past few years have seen an increase
of 54%, going from 4.8% in 2018 to 7.4% in 2020 (the most recent released list).

Below are the Top 30 companies and the female leaders who made last year’s list, and the universities they attended. The rankings that appear are where the company placed in the Fortune 500 list. Since the list was published, several of the women have left their positions. Each time, this is notated.
