[00:00] Frederick Moore: From Neural Newscast, this is Deep Dive, exploring the moments that shape today.
[00:10] Frederick Moore: I am Frederick Moore, and today on Deep Dive, we are examining a date that gave us one of the most enduring images of the 20th century.
[00:22] Frederick Moore: It is a day defined by high-stakes struggle on a volcanic island in the Pacific
[00:29] Frederick Moore: and a breakthrough in a school basement in Pittsburgh.
[00:34] Frederick Moore: Today is Monday, February 23rd, 2026.
[00:39] Nina Park: And I'm Nina Park.
[00:41] Nina Park: We are looking at February 23rd.
[00:44] Nina Park: While many know the photo of the flag raising on Iwo Jima, the details behind that moment
[00:50] Nina Park: and the later scientific victory over polio are far more complex than a single snapshot might suggest.
[00:58] Nina Park: It is a day where we see the best of human grit and scientific dedication.
[01:04] Frederick Moore: The year was 1945.
[01:07] Frederick Moore: The Battle of Iwo Jima was in its fifth day,
[01:10] Frederick Moore: a brutal conflict that would become one of the bloodiest in Marine Corps history.
[01:15] Frederick Moore: Nina, set the scene for us at Mount Suribachi.
[01:19] Nina Park: Mount Suribachi is a 550-foot dormant volcano at the southern tip of the island.
[01:26] Nina Park: On the morning of February 23, U.S. Marines from the 5th Marine Division
[01:32] Nina Park: successfully captured the peak and raised a small American flag.
[01:37] Nina Park: But the image the world remembers came later that afternoon.
[01:41] Frederick Moore: Yeah, that is the part often lost in the shorthand of history.
[01:45] Frederick Moore: The iconic photo by Joe Rosenthal actually shows a second larger flag being raised.
[01:51] Frederick Moore: Rosenthal was an associated press photographer who happened to be in the right place at the right time.
[01:58] Frederick Moore: He captured six men working in unison to drive that pipe into the ground.
[02:03] Nina Park: The identification of those six men has been a matter of historical record that required several corrections over the decades.
[02:12] Nina Park: We now know the group included Michael Strank, Harlan Block, Franklin Sousley, Ira Hayes, Harold Schultz, and Harold Keller.
[02:21] Nina Park: Tragically, Strank, Block, and Sousley were killed in action later in that same battle.
[02:28] Frederick Moore: It is a heavy legacy, Nina.
[02:30] Frederick Moore: That single photograph won a Pulitzer Prize and was in Sunday newspapers just two days later.
[02:37] Frederick Moore: It became a symbol of determination for a nation weary of war,
[02:41] Frederick Moore: even though the battle for the rest of the island would continue for weeks.
[02:45] Frederick Moore: It shows us how a single moment of perceived victory can sustain an entire campaign.
[02:52] Nina Park: Right.
[02:53] Nina Park: Moving from the battlefield to the laboratory, February 23rd also marks a significant victory in the realm of public health.
[03:01] Nina Park: In 1954, at Arsenal Elementary School in Pittsburgh, the first mass inoculation against polio began.
[03:09] Frederick Moore: Polio was a terrifying specter in the mid-20th century.
[03:13] Frederick Moore: Before the vaccine, the United States saw 15,000 cases of paralysis and nearly 2,000 deaths every year.
[03:22] Frederick Moore: Parents were afraid to let their children go to swimming pools or theaters during the summer months.
[03:27] Frederick Moore: It was a time of genuine public fear.
[03:30] Nina Park: The man behind the solution was Dr. Jonas Salk.
[03:33] Nina Park: He developed the killed virus vaccine,
[03:36] Nina Park: and the trial at Arsenal Elementary was the beginning of the end for the disease.
[03:41] Nina Park: What is truly remarkable, Frederick, is Salk's stance on the intellectual property of his discovery.
[03:48] Frederick Moore: Exactly. He famously asked, could you patent the sun?
[03:53] Frederick Moore: Salk chose not to patent the vaccine, effectively walking away from millions in potential profits.
[04:00] Frederick Moore: He wanted to ensure that distribution was as fast and as wide as possible,
[04:05] Frederick Moore: prioritizing human life over commercial gain.
[04:09] Frederick Moore: it remains one of the greatest examples of scientific altruism.
[04:14] Nina Park: His decision worked. Within years, the number of cases plummeted.
[04:19] Nina Park: It is a stark contrast to the way we often see pharmaceutical breakthroughs handled today,
[04:25] Nina Park: making the events of 1954 even more significant for the global community.
[04:30] Frederick Moore: While we consider these shifts in global history, we also have to look at the individuals born on this day
[04:36] Frederick Moore: who changed our cultural and intellectual landscape.
[04:40] Frederick Moore: Nina, we start in 1868 with W.E.B. Du Bois.
[04:45] Nina Park: That's remarkable.
[04:47] Nina Park: Du Bois was a titan of sociology and history.
[04:50] Nina Park: As a co-founder of the NAACP and the author of The Souls of Black Folk,
[04:55] Nina Park: he provided a profound analysis of the African American experience.
[05:00] Nina Park: His work on the concept of double consciousness remains a foundational text in understanding race in America.
[05:07] Frederick Moore: His influence cannot be overstated.
[05:10] Frederick Moore: He was the first African American to earn a doctorate from Harvard, and he spent his long life fighting for civil rights and pan-Africanism.
[05:19] Frederick Moore: It is a legacy of intellectual rigor and relentless activism that continues to inspire current generations.
[05:27] Nina Park: And on a different side of the cultural spectrum, we shared this birthday with two very prominent
[05:34] Nina Park: figures in modern cinema.
[05:36] Nina Park: Emily Blunt, born in 1983, has built an incredible range of work, from her breakout in The Devil
[05:43] Nina Park: Wears Prada to her recent acclaimed performance in Oppenheimer.
[05:48] Frederick Moore: Yeah, she has a way of anchoring a film.
[05:51] Frederick Moore: Whether it is a silent horror like a quiet place or a massive musical like Mary Poppins Returns.
[05:58] Frederick Moore: And then there's Dakota Fanning, born in 1994, who essentially grew up in front of the camera.
[06:05] Nina Park: Dakota became a household name at age seven with I Am Sam.
[06:09] Nina Park: Since then, she has navigated the transition from child star to a respected adult actress,
[06:15] Nina Park: with roles in War of the Worlds and more recently in Quentin Tarantino's Once Upon a Time in Hollywood.
[06:21] Frederick Moore: It is interesting to see the mix of voices born on this day, Nina.
[06:26] Frederick Moore: From the sociological depth of Dubois to the creative heights reached by Blunt and Fanning,
[06:32] Frederick Moore: they all represent a pursuit of excellence in the respective fields.
[06:36] Nina Park: No way.
[06:37] Nina Park: It really highlights how February 23rd is a day where individual talent and collective action both left their mark.
[06:44] Nina Park: Whether it was six Marines on a hill or a doctor in a Pittsburgh elementary school,
[06:49] Nina Park: today is about making a lasting impact.
[06:52] Frederick Moore: A Day of Symbols and Solutions.
[06:54] Frederick Moore: I am Frederick Moore.
