Alfred Beck Chapman (September 6, 1829 – January 16, 1915) was a Los Angeles real estate attorney and investor.

His grandfather, Robert Hett Chapman, was born in Orange, New Jersey, studied theology and was a pastor from 1796 to 1812, at which time he became president of the University of North Carolina at Chapel Hill until 1816.

On February 15, 1855, he became a Second Lieutenant, U. S. 1st Dragoon Regiment, March 3, 1855, being ordered on frontier duty, at Albuquerque, New Mexico Territory in 1856.

[4] While at Fort Buchanan, he also made the first census for the United States of the Pima, Papago and Maricopa peoples of Arizona.

Their law practice was confined chiefly to real estate transactions, and they made their fortunes by handling the large partition suits.

They hired the land surveyor, Frank Lecouvrier of Los Angeles, to map this tract, which they called Richland Farm District.

He married again after her death in 1883, and had one child by his second marriage to Mary L. Stephens, daughter of a pioneer California attorney and judge.

Chapman died on January 16, 1915, at the age of 85 in his residence near Sunny Slope in the San Gabriel Valley, "the result of heart failure following a severe cold."
