Albert has acquired a new gloss as one of the top <a href="https://nameberry.com/list/341/royal-names-for-boys">royal baby boy names</a>, a considerable upgrade from its serious, studious image (think Einstein, Schweitzer). 

Albert became popular in Britain following the 1840 marriage of Queen Victoria to the German Prince Albert and remained in vogue for 80 years. In the US, it's been on a downward slide for a century, though it's always ranked in the US Top 1000 and is a Top 100 name in England and Denmark.

Along with such stalwarts as Walter and George, it could now make a distinctive yet classic choice. Enlivening nickname Bertie is popular on its own in the UK.

Albert

The great philosopher's name is commonly used in Greek families, and is one that could work for daring, philosophy inclined American ones. 

Aristotle

Atticus, with its trendy Roman feel combined with the upstanding, noble image of Atticus Finch in To Kill a Mockingbird, is a real winner among <a href="https://nameberry.com/boys-names">boy names</a>. Atticus entered the US Top 1000 in 2004 and is a firm Nameberry favorite. 
 
The reason for the popularity of Atticus is less its ancient roots than Atticus Finch, the upstanding hero of To Kill A Mockingbird.. In fact so many people have been inspired by the character embodied by Gregory Peck that Atticus Finch was voted the greatest hero of American film by the American Film Institute. Harper Lee's recently-released novel Go Set a Watchman paints Atticus Finch in a less flattering light, though that doesn't seem to have impacted the rising popularity of the name.
 
Atticus derives from the Greek Attikos, meaning "from Attica," the Ancient Greek region that contained Athens. Atticus is a literary name in more ways than one. Before it became synonymous with Atticus Finch, the name Atticus was associated with Titus Pomponius Atticus, a Roman literary figure.
 Daniel Baldwin and Isabella Hoffman were ahead of the curve when they chose Atticus for their son born in 1996; since then Summer Phoenix and Casey Affleck named their little boy Atticus, and Tom Dumont made it the middle name for his son Rio.

Atticus

Ayn is a nonconformist name associated with controversial Russian-born writer and philosopher Ayn Rand, (born Alisa) author of The Fountainhead, who adopted it when she moved to the US in 1926.

Anaximander

The Brits say BARK-lee, but we pronounce it the same as the name of the California college: either way it's quite pretentious and of another era. 

Berkeley

This name of famed philosopher, mathematician and Nobel laureate Bertrand Russell becomes slightly more plausible with the French pronunciation, bare-TRAHN. Another noted bearer is French director and screenwriter Bertrand Tavernier.

David is an enduring worldwide classic, used from ancient times to the present day.
 David is derived from the Hebrew name Dawid, believed to come from the root dôwd, meaning “beloved”. The first famous David was the Old Testament second king of Israel: the shepherd boy who killed the giant Goliath, and later a warrior, poet, and powerful leader, wise but humanly fallible. He is an important figure in Judaism, Islam and Christianity, and later inspired many works of art, including Michelangelo’s colossal sculpture.
 Since then, there have been countless Davids of note in history, literature, and popular culture, including the patron saint of Wales — a translation of the Welsh name Dewi — two kings of Scotland. Then there’s Copperfield, Crockett, Bowie, Beckham, Letterman, Grohl, and many more. Celebrities who have chosen it for their sons include Jennifer Hudson, Bar Refaeli, and J.K. Rowling.
 In its international forms, David is steadily popular around the world, and ranks in the Top 10 names in Brazil, Austria, Armenia, Croatia, Bosnia and Herzegovina, and Israel.
 In the USA, David has never been out of the Top 40 boy names, but was at peak popularity in the mid-twentieth century, ranking in the Top 10 from 1936-1992. This means that, although it’s still given to thousands of boys each year, it has an “older man” feel to it. It ranks highest in states with a large Jewish population, and is still a Top 10 name in New York.
 After Daniel, David is the second most popular <a href="https://nameberry.com/search/boys-names/d">boy name starting with D</a>. Although fading a little in popularity, it remains a serious-yet-friendly classic with deep roots.
 If you’re looking to update David, perhaps as an honor name, the freshest alternatives are surnames deriving from David, including Dawes, Dawson, and Davies. You could also try an international variation, like Welsh Dai or Finnish Taavi.

The sophisticated Edmund and its nearly-identical French twin Edmond are coming out of mothballs now that Edward, inspired by Twilight, is once again a hot name.
 Edmund has had an enviable history, as evidenced by these quotes: "There is nobleness in the name of Edmund," says a Jane Austen character, and the poet John Keats once bemoaned, "Had my name been Edmund, I would have been more fortunate."
 Famous bearers include the English astronomer Edmund Halley, after whom the comet was named, poet Edmund Spenser, great Shakespearean actor Edmund Kean, and New Zealand mountaineer Sir Edmund Hillary. Literary Edmunds appear in King Lear,, Jane Austen's Mansfield Park, and Dickens's Little Dorrit.
 Edmund reached its highest point of popularity in the U.S. in 1914, when it was Number 130; it hasn't appeared on the list since 1997--making it even more attractive as an uncommon alternative to Edward.
 Eamon is the cheery Irish version.

Edmund

One of the most familiar <a href="https://nameberry.com/baby-names/160/german-names">German names</a>, with an upright Prussian image. Friedrich might just have been out for long enough to start coming back in.

Gabriel has become a biblical favorite, an angelic choice that's lighter and less patriarchal than some of his Old Testament brethren. Derived from the Hebrew name Gavri’el, Gabriel is taken from the elements gever, meaning "strong," and ’el, in reference to God.
 
In Abrahamic religions, Gabriel is the archangel who heralded the news of Jesus' birth, and appears in Christian, Jewish and Muslim texts. He presides over Paradise, serving as the angel of mercy, life, joy, judgment, truth and dreams. 
 In addition to all his other responsibilities, Gabriel is the patron saint of broadcasters and diplomats, and he governs Mondays and the month of January, making Gabriel one of the top <a href="https://nameberry.com/list/629/71-wonderful-names-for-january-babies">January baby names</a>. 
 
Gabriel has proven itself a friendly and appealing alternative to Michael, that other, long-reigning archangel. Gabriel enjoys remarkable international popularity, ranking in the Top 100 in countries as diverse as Israel and Iceland, Chile and Croatia. It is currently the Number 1 boys' name in France.
 Parents of Gabriels of varying ages include Mick Jagger and Jerry Hall, Daniel Day-Lewis and Isabelle Adjani, Jason Alexander, Meredith Vieira, and Mia Farrow.

Distinguished actor Hume Cronyn (who shared his father's name) put this unusual choice in the lexicon.

In the US, Emmanuel has held steady around the Top 200 for a quarter century now, but this variation has dropped off the Top 1000 for three of the past seven years. It was Number 974 in 2016.
 Immanuel Kant was a German philosopher in the eighteenth century.

Karl

Usually adding an e to the end of a name makes it more feminine, but Locke is at most recent count used only for baby boys. Still, this stylishly strong one-syllable name is theoretically gender-neutral.

Martin is one of those names like Arthur and Vincent and George that is in the process of throwing off its balding middle-aged image to start sounding possible again, used in full without the dated Marty nickname. 
 Notable Martins are too numerous to mention as the name has been so well used throughout time and in so many countries. Martin became part of the basic European stock of names, largely due to the popularity of the fourth century St. Martin of Tours. Also influential were the German founder of Protestantism Martin Luther and civil rights leader Martin Luther King (originally born Michael and renamed in honor of Martin Luther), eighth President Martin Van Buren, and influential philosophers Heidegger and Buber.
 More current Martins include actors Sheen and Short, writer Amis, and director Scorsese.
 Two books with eponymous Martin titles are Martin Chuzzlewit by Dickens and Martin Eden by Jack London.
 Martin also is enjoying popularity in countries such as Chile, Spain and Austria.
 Yes, a Martin revival appears to be right around the corner -- if only we can think of a new nickname.

Martin

German philosopher and revolutionary socialist Karl Marx will be most people's immediate association with this uncommon name. The author of The Communist Manifesto and Das Kapital is widely considered to be the father of international communism.

In the USA, Maurice was in the Top 200 for most of the 20th century; since 1990, however, it has been on a slow and steady decline. This name has the potential for some old-school cute nicknames such as Mo as well as the more trendy Reece.

Maurice

The name of one of the greatest Western philosophers is often used as a first name in its land of origin, Greece, and would make a really interesting, thought-provoking choice here. It is remembered here as the nickname of the memorable character played by Sal Mineo in the classic film "Rebel Without a Cause."
 And speaking of Greek philosophers, Germaine Clement of Flight of the Conchords named his little boy Sophocles.

Plato

This name is hanging on as Renee, thanks to Ms. Zellweger, and in newer forms Renae and Renny.

Rene

Philosophical surname that could make an unusual first for a red-headed girl.

Rousseau

One of many R- <a href="https://nameberry.com/boys-names">boys’ names</a> that started as a nickname for a redhead, Russell had a measure of popularity from the early twentieth century through the 1950s. But it's now lost much of its color -- except for a few dynamic bearers, actors Russell Crowe and Russell Brand and sports stars Russell Westbrook and Russell Wilson. 
 Russell has been much more common as a surname, whose many namesakes have included philosopher Bertrand, Gay Nineties entertainer Lillian, actresses Rosalind, Jane and Keri, actor Kurt, basketball star Bill and singer Leon.

Russell

Simone, the elegant French feminization of Simon, strikes that all-important balance between unusual and familiar, and it's oozing with Gallic sophistication. Dwayne "The Rock" Johnson has a daughter named Simone; Chris Rock used it in the middle place for his daughter, as did Kevin Kline and Phoebe Cates
 Two French philosophers are notable bearers of the name: feminist icon Simone de Beauvoir, author of the influential The Second Sex, and Simone Weil. The name might get a bit of a bounce via the two young Simones who shone in the 2016 Rio Olympics--Simone Bile, who set a US record high of four medals in a single Olympics, and Simone Manuel, who became the first African-American female swimmer to bring home a gold.
 The actress who played the lead in the iconic French horror movie Cat People is Simone Simon.

Simone

Quite common in traditional Greek families, but for others, we think Plato might be easier to handle. 

Socrates

This gentle Scandinavian name, soft and sensitive, is being discovered in a major way by parents in the US. It's most closely identified with the nineteenth century philosopher Soren Kierkegaard, but there have been modern fictional Sorens as well, in The Matrix Reloaded and the book series Guardians of Ga'Hoole, Charlie and Lola, and Underworld.

 In Scandinavia this name would be spelled as Sören or Søren, leading to it being pronounced "Sur-en". But with a plain old English "O", "Sorr-en" would actually be the correct (and more English-speaker friendly) pronunciation.
