Weekend Genius Challengs #21: Ti Kwan Leap
by Sandy - February 23, 2008 - 9:27 AM

With Leap Day coming up next Friday, I began to search my trivia mind for names of people that had been born on February 29. I recall a source saying Superman was born on that date, along with John Tesh. Oh, and “Froggy” from the Our Gang movie shorts. So I began to think about other unusual birthdates, and even examined my own. I realized that if I’d been born a week later, mine would be 4/5/67, which would’ve been cool because of the sequential numbers.

Froggy was born on "Leap" Day. Coincidence?Thus was born this Weekend Genius Challenge. Find a famous person, living or dead, whose birthdate is numerically unusual. 5/5/55 would be an example (all fives), as would 2/4/68 (all even numbers) or 1/6/1666. I’ll leave it to you to determine what makes the date unique. Post the person’s name and birthdate it in the comments below, and we’ll pick one of them at random to win a T-shirt of your choice from the mental_floss store. (Yes, we’ll check to make sure the date is correct.) Why a random pick? I’m taking Leap Day off. Hey, it only comes around every four years!

If you’re lucky, this Leap Day will be the last one you’ll ever have to live with an incomplete wardrobe. Wouldn’t you look great in one of these?

  11. although not a full date, one famous individual to be born on feb 29 was Fredric from the Pirates of Penzance.

  23. If this one gets chosen as random, throw it out because I don’t have evidence, but my grandpa would always rattle off how he was born on February 29th, 1944 at 9:22 am

    2.29.44 9:22

    Pretty nifty palindrome.

  24. 3/14/84 - 3*14=42
    *2
    —-
    84

  25. Thomas Arne composer of Rule Britannia:
    birthday 551778. Well, 55178 upside down spells “bliss” (which is fitting for the song).

  26. Jordin Tootoo, hockey player for the Nashville Predators, wears number 22 and was born on February 2nd…

  27. Only works for month and day, but Albert Einstein was also born on March 14th (3.14) however, in 1879, not 1915.

    Another, 2.7.18 Northern Irish painter Markey Robinson (the mathematical constant e 2.718… )

    and John Beckwith, composer

  30. 1.9.44 (Jan. 9, 1944) - Jimmy Page of Led Zeppelin - his birthday is the same as the year he was born (1944 is also an achilles number)

  31. David Yost (the original Blue Power Ranger) was born 1/7/71…again, another palindrome.

    Also, Adam Sandler was born 9/9/66 which is sorta cool.

  32. My family has a couple unusual dates -

    My sister 6/7/77
    My cousin 7/8/88

    I was born on 4/15 (income tax day - my mom almost called me Iris)
    My mom was born on 3/17 (St. Paddy’s day)

  33. The only boxer to hold world titles in three weight classes simultaneously, Henry Armstrong was born 12/12/12. He finished his career with a record of 150 wins, 21 losses, 9 draws, with 100 KOs.

  34. 1/1/11

  35. 7/6/54 - Allyce Beaslry - Ms. Depesto from Moonlighting

    4/3/21 - Harry Landers - Tv’s Ben Casey

  36. I was born 6/15/60. If you add the 1+5 you get 6/6/6 (that creeps me out). My husband was born 9/22/59. If you add the 2+2+5 you get 9, so its 9/9/9 and 9 flipped over is 6. OK, OK maybe not quite what your looking for, but amazing, at least to me. Can’t come up with anything for the kids, but my middle child was born October, 1998, or 10/9-8

  37. Mimi Kennedy, an actress born 9/25/1949 (9/25/49–all square numbers, 3^2, 5^2, 7^2).

    For fun, you can always go to IMDb and look up using the ‘on this day’ function. On the right, there is a box that says ‘Born Today’–if you click on all birthdays, then you can select by day (e.g., Feb. 23) and see everyone in their database born on that day.

  38. Canadian opera singer/teacher, Bruce Boyce: 9/02/10, as in Beverly Hills.

  39. My daughter’s birthday is May 5, 2005 (05/05/05), and is just a few days before my own b-day. I know she’s not famous now, but give her 20 yr’s or so and you never know! Either way we always have a good reason for a great Cinco De Mayo party!!

  40. Bob Griese (2/3/45) pro quarterback whose record in the Super Bowl is 2 wins and 3 losses.

  41. Anders Nøhr is a Danish professional footballer, who currently plays for the Danish Superliga side AC Horsens.
    His birthday is 3/9/81
    (3^2=9, 9^2=81, 81/3=27, 27/3=9)

  42. Pythagorean Triple
    John Newton 7-24-25

  43. Not a birthdate but my wife and I have hosted a party on the ‘unusual’ date annually since 2001, i.e. 01/01/01, 02/02/02, etc. This year we’ll have a cookout on August 8th. No particular theme, just a fun invitation to have our friends over for no reason but fellowship.

  44. Megan beat me to Heinlein’s birthday. Equally symmetrical is Carmen Miranda’s, 09/09/09.

    Football associations lead me to Bob Griese (2/3/45) and to Craig T. Hall (actor, of Coach fame) with a 4 digit match: 4/4/44.

    My favorite bends the rules a bit. It is Subrahmanyan Chandrasekhar, the Indian born Nobel Prize winning astrophusicist (for determining which stars would collapse to neutron stars (we’re safe, btw). Until he moved to the U. S. he would have written his birdate as 19/10/1910.

  45. Ralph Manza was born on 12-1-21. Mirror effect!

  46. Freddie Steele, born Frederick Earle Steele, born on 12/12/12.

    was recognized as middleweight champion of the world between 1936 and 1938. Steele was nicknamed “The Tacoma Assassin”

    He only lost two fights in the first ten years of boxing - WOW

  47. Since I see there is also another boxer who was born 12/12/12, I want to add that Freddie Steele became a Hollywood actor in the 40’s after his boxing career. Shots of his footwork can be seen in “Gentleman Jim” with Errol Flynn.
    He’s also in the boxing hall of fame…
    :)

  48. The main character from Pirates of Penzance was also born on February 29. It was why his captain refused to release him from servitude on his 21st birthday because officially he wasn’t yet 21 while technically he was.

  49. Sigmund Freud was born on 5/6/56 (1856, that is… but it is interesting that, at age 18 Freud began to study “psychodynamics,” a subject introduced the same year by his advisor in medical school).

  50. British Musician Steven Stapleton - 2/3/57 (first four prime numbers)

  51. Estonian Actor Marko Matvere was born 2/4/68

  52. I’m not famous but my birthday is 6/5/66

  53. I suppose there really isn’t a way for you to verify this, and he’s not famous, but my son’s birthday is 3/4/05 …I just remember it as 3/4/5

  54. I was born on 11.03.1978. Yeah I know..
    Spooky!

  55. My birthday and my first four digits of my social security number are the same….that’s not supposed to happen….it’s interesting to me anyway :)

  56. My daughter Trysten- 2/22/02. She’s famous- not right now, but she will be!

  57. Not famous, but my son was born on 2/1/00. Not since 12/11/10, 90 years, could you have a descending pattern like this.

  58. Me! 7.12.94
    7×12=84

  59. Me, I am famous in my own world! 9/8/76

  60. My daughter’s name is Novalee (named in part for the Chevy Nova). Her birth time was 4:42 pm, same as the Olds 442. I find the car references ironic!

  61. February 3rd, 1904
    02/03/04, Charlie “Pretty Boy” Floyd, bank robber, killer, and an FBI Most Wanted criminal, was born

  62. Hmmm…no one mentioned 8/8/08. I guess this is more of a cultural thing. 8 is a like number in the chinese culture. So 888 is like the 777.

    Even better is 1/6/08. 168 is also a “lucky” chinese number because when said 1-6-8 in chinese, it sounds similar to “One road to prosperity.” So there you have it.

    On the negative side, the number 4 sounds similar to ‘die’(as in death, not the process of coloring), so 4/4/04 was not a good day.

  63. Ok, not such a famous person, but really cool:

    My son was born 3/3/96

    3*3 = 9
    or
    3+3 = 6

    or circular 3*3=9(-3)=6(-3)= 3 so we get to start all over…

  64. My mom was june tenth, 1960, 6*10=60. My sister and I were both born on the 13th, september and october respectively, so my lucky number has always been 13. My fiance’s birthday is 12/1, so I guess he’ll do.

  65. Nick, 8 being a lucky Chinese number is why the Olympics in Beijing are starting on 8/8/08. Also, why cell phone numbers in China that have 8’s in them are more expensive, and the ones with 4’s in them are cheaper.(I kid you not- my cell number was cheap, no 8’s, but a bunch of 4’s!)
    But I digress… I always thought that my birthdate was cool sounding, 3/22/82, but there’s nothing mathematically significant about it. The kids I nannied for, the youngest two were born on 4/5 and 5/6 (the years don’t follow the pattern, but it’s still cool.)
