The Early Years: Monsters, Martians, and Moral Panic
The nineteenth century gave us some of the first fully realized, culturally impactful extraterrestrial beings. Thinkers like Percival Lowell, mistakenly believing he saw intricate canals on Mars, fuelled a fascination with a potentially older, wiser, or perhaps more desperate Martian civilization. This groundwork was violently subverted by H.G. Wells in his seminal 1898 novel, The War of the Worlds. Wells didn’t give us friendly explorers; he delivered terrifying, technologically superior invaders. His Martians were monstrous: vast, pulsing brains, wet mouths, and tripod war machines, embodying the dread of unchecked imperialism turned back upon the colonizer. They were, crucially, inhumanely cruel and coldly logical, establishing the template for the ‘Alien-as-Conqueror’ that would dominate the genre for decades. This early depiction served a profound cultural purpose. It was a safe space to process anxieties about rapid technological change, the brutal realities of European colonialism, and the inherent fragility of human civilization. The Martians’ weakness—our common cold—was the ultimate, ironic twist, a reminder that nature is the great equalizer, a narrative device we still see echoed today. The early 20th century, particularly in pulp magazines, codified a different type of alien: the Bug-Eyed Monster (BEM). These creatures were often reptilian, insectoid, or tentacled, designed for shock value on a dime-store cover. They were simplistic villains, often characterized by a lust for Earth women or global domination, a clear reflection of the often-simplistic narratives and conservative values of the era’s popular entertainment.The early ‘Martian’ trope, popularized by H.G. Wells, was less an exercise in speculative biology and more a direct commentary on the ethics of the British Empire’s colonial expansion. By presenting the Martians as ruthlessly efficient invaders, Wells forced his Victorian readership to momentarily experience the vulnerability and terror of the colonized, establishing a narrative framework where the extraterrestrial visitor serves as a powerful mirror for human societal failings. This narrative device continues to inform modern storytelling about first contact.
The Mid-Century Shift: Cold War Paranoia and Cosmic Hope
The mid-twentieth century, bracketed by the atomic age and the Cold War, dramatically altered the cultural blueprint for extraterrestrials. The invaders didn’t always arrive in visible ships; sometimes, they already walked among us. The 1950s saw the rise of the Infiltration Alien, creatures like the pod people in Invasion of the Body Snatchers. These aliens weren’t invading with heat rays; they were replacing us, stripping away our individuality and emotional capacity, an unmistakable allegory for the era’s profound fear of communism, conformity, and ideological subversion. However, this period also introduced the concept of the Benevolent or Observer Alien. In films like The Day the Earth Stood Still (1951), the alien Klaatu arrives not to conquer, but to warn humanity about its dangerous, self-destructive impulses (specifically, the development of nuclear weapons). This portrayal marked a significant shift: the alien was now sometimes the moral authority, the detached observer whose superior intellect and peaceful intentions stood in stark contrast to human aggression. These figures were often humanoid, clean, and stoic, suggesting that higher intelligence naturally leads to higher morality.Physical Forms and Psychological Impact
Our visual lexicon for aliens solidified during this time. Two forms became dominant:- The “Greys”: The small, large-headed, almond-eyed, slender-limbed figures, popularized by alleged abduction stories starting in the 1960s (notably the Betty and Barney Hill case), became the most recognizable and enduring image of an alien. They are often associated with psychological horror, medical experimentation, and existential helplessness.
- The ‘High-Evolutionary’: Often represented as luminous, translucent, or energy-based beings, these aliens (as seen in 2001: A Space Odyssey) are so far beyond us that their intentions are incomprehensible, tapping into humanity’s desire for transcendence and the fear of the utterly unknown.
