Carl Sagan
Childhood

Carl Edward Sagan was born in the Bensonhurst neighborhood of New York City's Brooklyn borough on November 9, 1934. His mother, Rachel Molly Gruber, was a housewife from New York City; his father, Samuel Sagan, was a Ukrainian-born garment worker who had emigrated from Kamianets-Podilskyi (then in the Russian Empire). Sagan was named in honor of his maternal grandmother, Chaiya Clara, who had died while giving birth to her second child; she was, in Sagan's words, "the mother she never knew." Sagan's maternal grandfather later married a woman named Rose, who Sagan's sister, Carol, would later say, was "never accepted" as Rachel's mother because Rachel "knew she wasn't her birth mother." Sagan's family lived in a modest apartment in Bensonhurst. He later described his family as Reform Jews, the most liberal of Judaism's four main branches. He and his sister agreed that their father was not especially religious, but that their mother "definitely believed in God, and was active in the temple and served only kosher meat." During the worst years of the Depression, his father worked as a movie theater usher.

According to biographer Keay Davidson, Sagan experienced a kind of "inner war" as a result of his close relationship with both his parents, who were in many ways "opposites." He traced his analytical inclinations to his mother, who had been extremely poor as a child in New York City during World War I and the 1920s, and whose later intellectual ambitions were sabotaged by her poverty, status as a woman and wife, and Jewish ethnicity. Davidson suggested she "worshipped her only son, Carl" because "he would fulfill her unfulfilled dreams." Sagan believed that he had inherited his sense of wonder from his father, who spent his free time giving apples to the poor or helping soothe tensions between workers and management within New York City's garment industry. Although awed by his son's intellectual abilities, Sagan's father also took his inquisitiveness in stride, viewing it as part of growing up. Later, during his career, Sagan would draw on his childhood memories to illustrate scientific points, as he did in his book Shadows of Forgotten Ancestors.

Describing his parents' influence on his later thinking, Sagan said: "My parents were not scientists. They knew almost nothing about science. But in introducing me simultaneously to skepticism and to wonder, they taught me the two uneasily cohabiting modes of thought that are central to the scientific method." He recalled that a defining moment in his development came when his parents took him, at age four, to the 1939 New York World's Fair. He later described his vivid memories of several exhibits there. One, titled America of Tomorrow, included a moving map, which, as he recalled, "showed beautiful highways and cloverleaves and little General Motors cars all carrying people to skyscrapers, buildings with lovely spires, flying buttresses—and it looked great!" Another involved a flashlight shining on a photoelectric cell, which created a crackling sound, and another showed how the sound from a tuning fork became a wave on an oscilloscope. He also saw an exhibit of the then-nascent medium known as television. Remembering it, he later wrote: "Plainly, the world held wonders of a kind I had never guessed. How could a tone become a picture and light become a noise?"

Sagan also saw one of the fair's most publicized events: the burial at Flushing Meadows of a time capsule, which contained mementos from the 1930s to be recovered by Earth's descendants in a future millennium. Davidson wrote that this "thrilled Carl." As an adult, inspired by his memories of the World's Fair, Sagan and his colleagues would create similar time capsules to be sent out into the galaxy: the Pioneer plaque and the Voyager Golden Record précis.

During World War II, Sagan's parents worried about the fate of their European relatives, but he was generally unaware of the details of the ongoing war. He wrote, "Sure, we had relatives who were caught up in the Holocaust. Hitler was not a popular fellow in our household... but on the other hand, I was fairly insulated from the horrors of the war." His sister, Carol, said that their mother "above all wanted to protect Carl... she had an extraordinarily difficult time dealing with World War II and the Holocaust." Sagan's book The Demon-Haunted World (1996) included his memories of this conflicted period, when his family dealt with the realities of the war in Europe, but tried to prevent it from undermining his optimistic spirit.

Soon after entering elementary school, Sagan began to express his strong inquisitiveness about nature. He recalled taking his first trips to the public library alone, at age five, when his mother got him a library card. He wanted to learn what stars were, since none of his friends or their parents could give him a clear answer: "I went to the librarian and asked for a book about stars and the answer was stunning. It was that the Sun was a star, but really close. The stars were suns, but so far away they were just little points of light. The scale of the universe suddenly opened up to me. It was a kind of religious experience. There was a magnificence to it, a grandeur, a scale which has never left me. Never ever left me." When he was about six or seven, he and a close friend took trips to the American Museum of Natural History, in Manhattan. While there, they visited the Hayden Planetarium and walked around exhibits of space objects, such as meteorites, as well as displays of dinosaur skeletons and naturalistic scenes with animals. As Sagan later wrote, "I was transfixed by the dioramas—lifelike representations of animals and their habitats all over the world. Penguins on the dimly lit Antarctic ice a family of gorillas, the male beating his chest an American grizzly bear standing on his hind legs, ten or twelve feet tall, and staring me right in the eye."

Sagan's parents nurtured his growing interest in science, buying him chemistry sets and reading matter. But his fascination with outer space emerged as his primary focus, especially after he had read science fiction by such writers as H. G. Wells and Edgar Rice Burroughs, stirring his curiosity about the possibility of life on Mars and other planets. According to biographer Ray Spangenburg, Sagan's efforts in his early years to understand the mysteries of the planets became a "driving force in his life, a continual spark to his intellect, and a quest that would never be forgotten." In 1947, Sagan discovered the magazine Astounding Science Fiction, which introduced him to more hard science fiction speculations than those in the Burroughs novels. That same year, mass hysteria developed about the possibility that extraterrestrial visitors had arrived in flying saucers, and the young Sagan joined in the speculation that the flying "discs" people reported seeing in the sky might be alien spaceships.
