HOW THE HOLIDAY CAME TO BE

An unsigned holiday for a very old name.

Research has not identified a founder, an establishing document, or any explanation for why the observance falls on January 19. The name itself is far older and far better documented than the day that honors it.

INTRO

A three year old's drawing that ended up naming a human ancestor

In November 1974, a team digging at Hadar in Ethiopia began lifting a fossil skeleton out of a hillside. That night in camp a Beatles record played over and over, and before the night was out the skeleton had a name. National Lucy Day, on January 19, belongs to that name.

The song had a Lucy of its own. John Lennon said it came from a drawing his son Julian, then three, had made of a nursery school classmate, and Paul McCartney remembered the title written across the top of it in a child's handwriting.

The word underneath all of it is older still. Lucy is the English form of Lucia, and its root is lux, the Latin for light. A name meaning light reached a skeleton 3.2 million years old by way of a crayon drawing and a pop song.

ORIGINS

Lucy Day history

INTRODUCTION

Lucia died at Syracuse, in Sicily, in 304. She was one of the earliest Christian martyrs, and she became the patron saint of the city. Her feast settled on December 13.

The name she carried was already a word. Behind Lucia sits the Latin lux, light, which is why her midwinter feast grew into a festival of light kept across Sweden, Norway, Italy and Swedish-speaking Finland.

CHAPTER 01

Light in her hair

In the old Swedish almanac, Lucia Night was the longest of the year. The first recorded white-clad Lucia in Sweden appeared at a country house in 1764. Stockholm proclaimed its first Lucia in 1927, and the procession still moves by candlelight, the girl at the front wearing what Swedes call light in her hair.

CHAPTER 02

The Lucy who would not change her name

America made its own Lucys. Lucy Stone graduated from Oberlin in 1847, the first Massachusetts woman to earn a bachelor's degree. At her wedding eight years later she and Henry Blackwell read out a protest they had written against the legal terms of marriage.

She kept her own name. When she refused to pay city taxes she could not vote on, the constable auctioned her household goods to cover them.

CHAPTER 03

Down to almost nothing

Then the name went quiet. Lucy ranked 44th among American girls when the national record began, and it slid for most of the century that followed. It bottomed out below five hundredth place.

Television did not rescue it. I Love Lucy topped the American ratings for four of its six prime time seasons, and across those years the rate of newborn Lucys ticked up briefly and then resumed falling. Lucille, the star's own given name, dropped by more than a third across the same seasons.

CHAPTER 04

A holiday without a signature

The observance is the newest and thinnest part of the story. Its founder, its establishing document and its reason for the January date have all stayed out of reach. That leaves a name day for a name whose own feast has been fixed to December 13 for centuries.

What the record does show is the name coming back, and its biggest year yet is the most recent one.

TIMELINE

NASA's Lucy flies past the asteroid named for the fossil and finds it is a binary.

WHY THIS DAY MATTERS

Why National Lucy Day Matters

SCIENCE

One nickname now labels a fossil, a spacecraft and an asteroid.

NASA named its first mission to the Jupiter Trojan asteroids after the fossil, and the International Astronomical Union approved Dinkinesh, the fossil's Ethiopian name, for the first asteroid that mission visited. A nickname coined in a field camp now sits in the official catalogue of the solar system.

MEMORY

Ethiopia kept its own name for her

At home the skeleton is Dinkinesh, which means you are marvelous in Amharic, and the fossils themselves are held at the National Museum in Addis Ababa. When the spacecraft found a moon at the asteroid, the team called it Selam, an Amharic greeting meaning peace.

LANGUAGE

The light in the name survives translation

The same root produced Lucie in French, Luz in Spanish, Łucja in Polish and Liùsaidh in Scottish Gaelic. A name day for Lucy is a name day for a word that kept its meaning in every language it entered.

How to Observe National Lucy Day

EDITOR'S PICK

Read the record of a namesake reformer

The National Park Service keeps a biography of Lucy Stone, including the protest she read at her own wedding. Her dying words were make the world better.

VISIT

Visit the fossil's museum record online

The Smithsonian's Human Origins Program keeps a specimen page for AL 288-1, the catalogue number behind the nickname. It gives the site, the discoverers and the species behind the nickname.

FOLLOW

Follow the spacecraft that carries the name

NASA's Lucy mission publishes its asteroid target list and flyby dates. Its Trojan targets ahead include Eurybates, Polymele, Leucus, Orus and Patroclus.

BAKE

Bake the saffron buns of the Lucia feast

Swedish Lucia tradition calls for lussekatter, sweet saffron buns served with coffee. The Swedish Institute notes the custom of serving them goes back to the 1880s.

LOOK

Look the name up in the naming data

The Social Security Administration publishes a national count for every name and year since 1880. Reading Lucy's line from top to bottom shows a fall and a recovery rather than a straight climb.

Test your knowledge

How well do you know National Lucy Day?

1 / 8

What does the Latin root behind the name Lucy mean?

Answer

No. It is an unofficial observance with no legal standing, and a search of the Federal Register turns up no recognition of it, so offices and schools stay open.
