My grandfather was a death row doctor

Eusebio Martinez was polite — even happy — as he entered the death chamber that August night in Huntsville in 1960. He may not have understood his time was up.
A few years earlier, Martinez had been convicted of murdering an infant girl whose parents had left her sleeping in their car while they visited a Midland nightclub. He’d been ruled “feeble-minded” by multiple psychiatrists and had to be shown how to get into the electric chair.
As he was strapped in, a priest leaned in and coached him to say “gracias” and a simple prayer. Just before the first bolt knifed through his brain, Martinez grinned and waved at the young Houston doctor who would declare him dead a few minutes later.
That doctor was my grandfather.
