Nurse Symbols 101: A Brief History

Nursing badges, healthcare-themed jewelry, and uniforms like scrubs are adorned with symbols signifying the authority and duty of nurses. These symbols provide immediate recognition. Even without scrubs, if someone wears one of these icons, their profession as a nurse is clear. Two such symbols synonymous with nursing are the caduceus and the oil lamp, each with distinct origins and meanings. Let's explore these symbols and their histories.

In this discussion, we'll cover:

• The caduceus sign
• The Staff of Asclepius
• The oil lamp
• Classic cap and attire

The Caduceus: The Emblem Most Identified with Nursing

In Greek lore, Hermes, the deity of transitions, wielded the caduceus, a staff entwined by two serpents, sometimes with wings. But what’s the significance of snakes in medicine? In ancient Greece, snakes symbolized endurance and eternal life. While medicine may not promise immortality, it does extend life. Additionally, in a religious context, Moses used a bronze snake on a pole to heal snakebites around 1400 BC. Thus, the snake’s association with healing has persisted throughout history.

In 1902, the U.S. Medical Department adopted the caduceus as its emblem, extending it to the medical officer’s attire. Various U.S. medical branches, such as the U.S. Navy Pharmacy Division, Military Nurses, and U.S. Public Health Service, adopted it as well. Despite its widespread association with healthcare, the caduceus was mistakenly linked to medicine.

The Caduceus Mix-Up

Analyzing the caduceus design explains why it became a medical symbol. Historically, around 76% of healthcare sectors used it, though many have since switched to the more fitting Staff of Asclepius. This symbol, a rod with a single snake, is carried by Asclepius, the Greco-Roman god of healing. Despite this misalignment, some healthcare entities continue to retain the caduceus due to its public recognition.

The Oil Lamp: A Less Common Symbol

In the history of nursing symbols, one cannot overlook the iconic British figure who epitomized modern nursing practice, associated with the oil lamp. The lamp represents Florence Nightingale, who used it during her nighttime care of the ill. The lamp illuminated her path as she tended to soldiers during the Crimean War in the 19th century. Her dedication set a precedent for future nurses, sharing her skills and compassion with those in need.

Florence Nightingale's work inspired young women to pursue nursing and offered them educational opportunities. New nurses often recite the Nightgale Pledge and might receive a lamp pin, honoring this pioneering nurse. Some nursing bodies, such as the International Council of Nurses, incorporate the lamp in their logos to honor her legacy.

Traditional Cap and Attire

Though now largely obsolete, the classic nurse cap and uniform are worth mentioning. Vintage TV shows often depict nurses in their recognizable caps. These caps originally honored deaconesses who cared for the sick. Florence Nightingale, recognized as the modern founder of nursing, sought to retain this tradition while providing a distinct nurse appearance. The caps also helped keep nurses’ hair tidy and hygienic.

Early nursing outfits included starched white dresses, stockings, and shoes, but styles began to evolve in the 1950s and 1960s as more men entered the nursing profession. By the 1990s, scrubs became popular for their comfort and practicality in healthcare settings. Today, nurses can often be found in more flexible, breathable clothing options tailored to both comfort and function, with no need for a starched dress or cap.
