In a 10-inch sauté pan over medium heat, warm the syrup and then add the butter. Stir until the butter is melted, about 2 minutes. Stir in the cinnamon, nutmeg, and salt.
Add the wedges of pear and simmer, basting frequently, until the pears are tender when pierced with a knife, about 10 minutes. Set aside and keep warm (The maple-glazed pears can be made ahead, cooled, covered, and refrigerated for up to 3 days. Re-warm before serving.)
To make the french toast, combine the eggs and milk in a medium bowl and beat until well combined. Add a pinch of salt. Heat a griddle or large skillet over medium-high heat. One at a time, dip a slice of bread into the egg mixture, coating both sides of the bread thoroughly. Dip as many slices as will fit on the griddle and reserve the rest for a second batch. Lightly butter the griddle or pan and arrange the coated slices in the pan. Cook on one side until nicely browned and then turn and brown the other side. Keep warm while you make the second batch.
Have ready 4 warm plates. Arrange 2 slices of French toast on each plate and top with some of the maple-glazed pears, spooning extra sauce over top. Serve immediately.
