Born to an Italian-American family and known as “Young Tommy,” D’Alesandro had a political upbringing.
“His life and leadership were a tribute to the Catholic values with which we were raised: faith, family, patriotism. He profoundly believed, as did our parents, that public service was a noble calling and that we all had a responsibility to help others,” she said.
Devout Catholics, Pelosi said her brother is now with the angels.
“All his life, Tommy worked on the side of the angels. Now, he is with them,” she said.
D’Alesandro is survived by his wife Margaret, his children Thomas, Dominic, Nicholas, Patricia and Gregory, and his grandchildren “whom he adored,” Pelosi said in the statement.
Baltimore Mayor Jack Young, a Democrat, expressed his condolences to Pelosi and the D’Alesandro family in a statement Sunday, saying the former mayor will be “remembered for his commitment to and love for” the city.
“He guided the city at a tumultuous time and made important strides while in office like creating summer recreation programs for youth, removing racial barriers in employment and education and laying the groundwork for what would become the world-famous Inner Harbor,” Young said.
