His voice first rode the air waves as this nation fought the Second World War.
In the nearly seven decades since, that same voice has more than earned Leland Milo Hamilton a living. It made him a legend.
Fans for no fewer than seven big league clubs have counted on his steady, insightful call. It's been a Hall of Fame career that cast the Iowan in an enviable role for one of baseball's monumental moments.
"Swinging, there's a drive into left center field! That ball is going to be gone! It's 715! There's a new home run champion of all time and it's Henry Aaron," Hamilton broadcasted in 1974.
"Ruth himself thought the record would never be broken," Hamilton said of the career moment he deems most significant.
In 1985, Hamilton came to Houston and dug roots that have held firm for 28 seasons, his description from the booth forever intertwined with Astro memories. Few fans can forget from Mike Scott's play-off clinching no-hitter to Craig Biggio's 3,000th hit.
Longtime Houston sports journalist Kenny Hand said the years have allowed Hamilton to reap an uncommon degree of loyalty from those certain to miss a voice so familiar.
"Milo's last game tonight is a real milestone," Hand said. "I think there will be a lot of people get choked up."
When Milo signs off, only Dodger great Vin Scully will have called more seasons in the "Bigs".
"Let the kids have something to shoot for," Hamilton joked.
