On Thursday (April 19), TIME announced their annual TIME 100 list. The list is designed to highlight the most influential people in the world stemming from different categories: pioneers, artists, leaders, icons, and titans, with plenty of overlap between the categories. The publication then has a well-known figure write up a brief description as to why the person was worthy of the honor.

Not all of the winners are well-known, though. Here are the TIME 100 winners -- one from each category -- that deserve more recognition.

1. Jan Rader - Pioneer

Rader earned her place on the TIME 100 list by becoming the first female fire chief of a professional fire department in the state of West Virginia.

Her job goes beyond putting out flames on the front lines, though -- she also plays a critical part in battling the opioid epidemic that has taken hold across the United States, especially in states like West Virginia.

2. Lena Waithe - Artist

Waithe began to earn recognition as an actress on Netflix's "Master of None," but she also served as a writer. The 2017 episode "Thanksgiving," autobiographically details her own coming-out story, and drew rave reviews and a historic Emmy victory as the first black woman to win in the Outstanding Writer in a Comedy Series category.

Since then, she's also helmed the Showtime show "The Chi."

3. Jacinda Ardern - Leader

This TIME 100 leader may not have nuclear codes in her arsenal, but she does have the honor of being the youngest female head of state in the world, named Prime Minister of New Zealand when she was just 37 years old. She conducts herself from a progressive standpoint, believing in same sex marriage and pro-choice options. She's also pregnant, much in the same way Tammy Duckworth recently was here in the United States.

4. Sinta Nuriyah - Icon

Once upon a time, she was the First Lady of Indonesia.

Now, she's arguably so much more. The TIME 100 recipient is considered an interfaith leader within her community, leading interfaith meals during Ramadan, much to the dismay of hard-line Muslims within the country. Two and a half decades ago, she overcame a paralyzing car accident to earn her degree -- she's incredible.

5. Adam Neumann - Titan

Neumann is the co-founder of WeWork, a company striving to change the way people work and live. WeWork has created communal spaces around the world that inspire collaboration and enjoyment of the workday, rather than simply clocking in and out. It's a model the rest of the world is taking notice of, as evidenced by his TIME 100 selection.
