Here is buried our dear father our teacher the Rabbi Mordechai son of Mr Dov Ber. Died the 23rd of Adar I 5689.

The title does technically signify that Max was an ordained Rabbi, but it is sometimes used incorrectly as an honorific title. In a leapyear the month of Adar is repeated, hence the date of Adar I.
