     Their reunion was unlike any other.  Graduating from the Macon, Georgia,  class of 1959 gathered

together in 2009, even though many of them never had an opportunity to meet during their high school

days.

     Schools in the 1950's, like most other public locations, were segregated (隔离)in Georgia. Kids were

forced to attend different schools depending on the color of their skin, and those with white skin were

further separated by gender. Fifty years later these people who were not allowed to associate with each

other were finally able to connect.

     It all began with the personal journey of a man named Tom Johnson. He grew up in Macon and

enjoyed a very successful career which included serving as the publisher of the Los Angeles Times and

president of CNN. Tom's life changed drastically over the years, but he still felt the desire to reconnect

with his roots.

     In 2005 Johnson returned to Macon with his son, Wyatt. As the pair drove around town,  the father

recounted high school stories to his son. He talked about how students attended one of three schools:

BallardHudson, Lanier or Miller. Wyatt looked over at his father and said: "Dad  think about how

many friends you missed getting to know."

     Johnson thought about the people he never got the chance to meet. He decided to do something

about it.

     The first step was to find people who graduated from all three schools. Johnson wrote to each person

and proposed they all get together for a luncheon. He explained that even though they were kept apart

during their youth, they didn't have to be separated any more. His classmates received the message with

open hearts. A reunion date was set for October.

      More than 200 former Macon students traveled hundreds of miles to reunite with people who went

to high school with them. It was an unprecedented event, former students coming together to make up

for the time they had lost during the days of segregation.
