In 1988, voters narrowly elected a former tax master named Mark Davidson to the bench. And the rest is history -- years, decades, even centuries of it, as Davidson continues his studies of the rich legacy of law and justice in Harris County. Of course, Davidson has more than earned his robe in the regular work of ruling on civil cases through the years. But his dedication to the courts, and county, really comes alive in his never-ending fascination with the foundations of law in Houston. In this era of ever-changing judges and utter lack of regard for the past, it's more than a little refreshing to see that kind of reverence for what was. As for his standing among his peers, Davidson was elected chief administrative judge for the county -- the historian becoming part of the rich heritage he treasures.
