In a food processor, combine cream cheese and butter. Then add in sugar and salt, process until smooth (dough will be sticky).
Turn dough onto a parchment lined baking sheet, and with lightly floured fingers, pat dough into an 8-inch circle with a slightly raised edge.
For filling, combine 1/4 cup sugar and lemon juice.
Leaving skin on, cut pear in half lengthwise, core, and cut into 1/4 inch slices.
Toss with lemon juice mixture.
Drain liquid and arrange around the border of the dough, overlapping slightly.
Arrange the remaining slices in the center. Sprinkle top with remaining 1 1/2 Tbsp sugar and cinnamon.
Bake at 400°F for 25-30 minutes.
