I’m a bit of a Carl Sagan junkie. I suppose it started the evening before Thanksgiving break my junior year, when my ride changed plans to leave the next morning. With an evening free, I scanned HULU for a show to kill time with. It recommended Cosmos, and after reading the glowing comments, I decided to check it out.
The name Carl Sagan was familiar, and I had seen his parted hair, turtleneck, and beige jacket parodied on television. I had also heard his famous Pale Blue Dot monologue at a talk from Bill Nye, who respected Sagan. I even met a professor from Cornell who got his office, replete with a hidden foot pedal to call campus police for unwanted visitors.
But the pieces didn’t connect.
The strangely nostalgic piano and synth-string theme played over an intro of star fields and passing nebula. The café around me softened into a whimpering white noise of scuffing tables, chatting workers, and clattering cups. Sagan spoke, his iconic cadences seeming to pick out words with the precision of tweezers.
“The sky calls to us,” he said. “If we do not destroy ourselves, we will one day venture to the stars.”
From then on, I watched the entire series. I didn’t have one of those day-long or night-long vigils pounding back each episode. They were too long for that, too rich. It took me a few months to finally finish, and in the meantime, I heard more talks and audiobook excerpts on YouTube where I found an entire community of “Saganites.”
I didn’t take long to realize that Sagan was a big deal.
Born in 1934, Carl Sagan grew up in a Jewish working-class neighborhood in New York City and got his earliest education in public schools. His father emigrated from Ukraine as a boy, while his mother grew up on the edge of poverty, a housewife from New York.
Both were smart and driven, and encouraged young Sagan and his only sibling Carol to learn. Sagan read library books, including one about the stars, which ignited his passion for science and the universe. As he recounts in his final book The Demon Haunted World:
“The crystallizing moment came when I first caught on that the stars are mighty suns, when it first dawned on me how staggeringly far away they must be to appear as mere points of light in the sky. I’m not sure if I even knew the meaning of the word ‘science’ then, but I wanted somehow to immerse myself in all that grandeur.”
A further crystallization occurred when he attended the 1949 World Fair, realizing that science could improve the world.
Sagan studied at The University of Chicago, through a scholarship, where he received the liberal “Great Books” education, and eventually got his doctorate in astronomy there in 1960. After two years as a postdoctoral fellow in Biology at Berkeley and Stanford, he became an assistant professor in the Harvard department of astronomy.
When the school denied him promotion, he moved to Cornell in 1968, where he worked until his death in 1996 from pneumonia, a few months after finding that he was in remission of myelodysplastic syndrome. He married three times, had five children, and left behind a staggering collection of work, both popular and scholarly.
As Frank Rhodes, the Cornell President, summarized, “I want to salute Carl Sagan … as the embodiment of everything that is best in academic life … in scholarship, teaching, and service.”
Most people know Sagan from his role in the 1980s series Cosmos, but he began as a respected researcher, professor, and lecturer–activities that continued throughout his life. Without this background, his other role would have been much harder.
His early research challenged the prevailing myth at the time that Venus had an earth-like atmosphere. His team proposed the now-established view that it’s hellishly hot and dense, replete with sulfuric rainclouds. He also studied the Martian climate and was an early proponent of extraterrestrial research, becoming one of the founders of SETI.
His later research–the famous TTAPS papers–detailed the models of nuclear winter, which helped spur nuclear disarmament during the Cold War.
His other role as a popularizer of science began with articles and lectures, including one for National Geographic in 1967. He also hosted a series symposiums based on debunking pseudoscience–one of his lifelong quests–that began in 1969.
These increased his popularity and established his reputation, but his breakthrough came when his well-reviewed book The Cosmic Connection landed him a spot on the Tonight Show with Johnny Carson in 1973. His good looks, clear descriptions, and scientific acumen captured the audience and thrilled Carson, who invited him back 26 more times in the following 13 years.
This fame culminated and peaked in the series Cosmos, which started production in 1977, airing September 1980. Around the same time, he also began his lifelong relationship and professional partnership with Ann Druyan. The two commitments overwhelmed Sagan, forcing him to cancel classes and neglect his research for a span.
As the series aired, he became an instant celebrity. People asked for autographs at restaurants, his picture appeared on popular magazines, death threats and fan letters flooded the mail, and his price to lecture increased to five figures. Time described him as the “Showman of Science” and the “prince of popularizers,” the sorts of labels that stuck with him for the rest of his life, even after fame receded in the early 90s.
In this capacity, I first saw Sagan, like most of his fans: he was an excited teacher who couldn’t help explaining what he loves most. He was clear-headed, welcoming, and informed, and I couldn’t help but listen.
The timing was perfect. In November, a few days before I first watched Sagan, I started taking antidepressants. I was in a bad state: train wrecked by the symptoms and near-suicidal. Things only got worse as my body adjusted to the pills, with patchy highs succumbing to crushing lows. I thought I had no point to live, and the urge to escape the pain increased.
But, influenced by Sagan, I started looking at the stars and thinking of space. It brought me back to my childhood, when my father and I stargazed. In silence, we plumbed the spattered tapestry with a thin telescope, prodded the dark with our pupils, and scoped out craters on the moon.
Sagan reanimated that love for space and that curiosity for the world.
The world expanded, becoming a wealth of opportunities and potential learning. I got excited about science again and started quoting Sagan’s quips about skepticism, open-mindedness, and creativity. I became a Saganite.
Later, I read more about Sagan, including the negatives. Like how his wives and children complained that he didn’t spend enough time with them, or how he often insisted on being the center of attention, earning the scorn of many colleagues. One marriage crisis almost killed Cosmos during production.
But, like any person, Sagan wasn’t merely the turtle-neck wearing teacher on television with those bright eager eyes and rolling cadences. He had problems, just as we all do. We don’t have to ignore or condone them, but we must accept that our black-and-white distinctions of good and bad rarely do any real human justice. They’re simply too strident. People are too imperfect–a “crooked timber” as Immanual Kant put it.
When I finally did finish the Cosmos series, long after I beat back my depression, the day was late, and the house was asleep. The closing credits rolled, as the nostalgic piano and synth-strings theme occupied the silence. I started crying.
Sagan, for all his flaws opened my eyes in a time when I needed them opened. He rekindled my love of life and provided a candle in the demon-haunted world of depression. Doing so, he probably saved my life. And I would miss him. But I knew that the imprint he left would linger, and this made me happy.
Reading all of the loving comments and blog posts about him online only solidified this further. “He was my favorite teacher,” said one. Another, “He’s the reason I’m a scientist.” Or a third refrain, “He will be missed.”
A few months later, I visited his grave and left a note, held down by one of the rocks left by Jewish mourners. It simply said, “Thank you.”
