Fans and aspiring time lords of all ages convened at the DeKalb Public Library for a celebration of the British cult-classic television show “Doctor Who.”

The science fiction show is celebrating its 50th anniversary this week. Fans gathered at the DeKalb Public Library, 309 Oak St., to celebrate all things Who.

“Whovians” are anticipating the upcoming 50th anniversary special “The Day of the Doctor” on Dec. 23, which will feature an appearance of the Twelfth Doctor, who will be played by Peter Capaldi.

Torry Leverton, 15, convinced the library to host the event after similar events were held for the Harry Potter and Star Wars series.

“It would have been unacceptable to not celebrate ‘Doctor Who’ alongside those other franchises,” Leverton said.

Leverton likes “Doctor Who” because “it displays humanity, its faults and its flaws, and how [the Doctor] influences humanity to do their best rather than fall down to their worst.”

The series has been an ongoing narrative for 50 years. The Doctor’s ability to “regenerate” has allowed for several actors to take the helm of the TARDIS, his time machine.

“‘Doctor Who’ originally started out as an educational program but gradually evolved into the sci-fi adventure show we have today,” said Elizabeth Poweren, reference librarian and long-time fan. “[The Doctor] is very quirky, but he has very definite ideas of good and evil. He has a lot of power, but he doesn’t always use it.”

Darcy Tatlock, tween coordinator at the library, hosted the all-ages event.

“The Doctor is quirky and fun and can appeal to any age,” Talek said.

Activities at the event included a costume contest, Doctor Who-themed snacks, like tea and fish sticks with custard, and discussion.

Matt Angel, 13, of DeKalb, was excited for the event. Angel attended the event dressed as the Eleventh Doctor, Matt Smith.

“It’s not like something you see on TV every day,” Angel said. “It’s very unique. It’s not every day you turn on the TV and somebody walks inside a phone box that’s bigger on the inside.”

Daniel Leverton, 8, of DeKalb, showed up in a homemade Dalek costume that covered him from head to toe. The costume was made of cardboard, and he wore a laundry basket on his head and carried a plunger and whisk for lasers.

“I like the daleks because they’re my favorite villains, but I like the whole thing,” Leverton said.
