Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE department (dept_code VARCHAR, dept_name VARCHAR)
TABLE: CREATE TABLE professor (prof_office VARCHAR, emp_num VARCHAR, dept_code VARCHAR, prof_high_degree VARCHAR)
TABLE: CREATE TABLE employee (emp_fname VARCHAR, emp_num VARCHAR)

### Question ###
Find the first name and office of history professor who did not get a Ph.D. degree.

### Accurate SQL ###

SELECT T2.emp_fname, T1.prof_office FROM professor AS T1 JOIN employee AS T2 ON T1.emp_num = T2.emp_num JOIN department AS T3 ON T1.dept_code = T3.dept_code WHERE T3.dept_name = 'History' AND T1.prof_high_degree <> 'Ph.D.'
